Minecraft: Java Edition has been obfuscated since its release. This obfuscation meant that people couldn’t see our source code. Instead, everything was scrambled – and those who wanted to mod Java Edition had to try and piece together what every class and function in the code did.
Modding is at the heart of Java Edition – and obfuscation makes modding harder. We’re excited about this change to remove obfuscation, as it should make it quicker and easier for modders to create and improve mods. Now you won’t have to untangle tricky code or deal with unclear names. What’s more, de-bugging will become more straightforward, and crash logs will actually be readable!
surprisingly fantastic and consumer friendly move from mojang, good on them

I have been playing re-console mod pack lately because I prefer 4J’s version of Minecraft the most.
Be nice if Minecraft was released on Steam so Linux users didn’t have to emulate an Android device just to play it.
Are you talking about the Bedrock edition or something? Because there are plenty of Java edition launchers available that even perform better than the Windows version
MultiMC in the house!
I think prism launcher is better these days (it’s a fork of multimc but with more stuff)
I’ll give it a look thnx
pretty sure it lets you import all your multimc instances so it’s a pretty easy transfer
I play the Java edition on Debian with mods from modrinth and don’t require emulation etc.
What are you talking about? When was the last time you tried this?
They’re talking about Bedrock edition, unless there’s some new method of running it that I’m not aware of. Minecraft Bedrock is available as a UWP app through Microsoft Store, which is only available on Windows, phones and consoles. It is not compatible with Steam, Wine, Proton or Linux in any way, The only known way to run Minecraft Bedrock on Linux is to install the Android App for Minecraft Bedrock in an Android emulator, there is a wrapper called MCPLauncher for this purpose.
Alternatively, you can use a translation layer like GeyserMC to use Java edition in a way that’s interoperable with Bedrock, but the Bedrock edition itself is not currently available on Linux.
That makes sense. I’ve never wanted to play bedrock so I’ve never tried.
Sorry other poster.
That’s fair, I hate it too. Java is way better, mine is so heavily modded I can barely stand vanilla Minecraft anymore. The only reason I know what a shitshow Bedrock on Linux is, is because my niece was at first only allowed to play on Switch and that’s only properly compatible with Bedrock, and she likes to show me around her worlds that she works on. I eventually convinced her parents to give her access to something that would let her play Java instead and since then we’ve only looked back at Bedrock once, and she was disappointed too haha.
Nice I just got back into all the mods 10 last night
They started providing deobfuscation maps 6 years ago
TIL
They should officially support the mod loaders at this point
Playing minecraft without mods as an adult is like eating a plain potato, or like going to a party without inebriating substances.
Why not go open source? What are they so afraid of, given anyone can now see the source code by using a simple tool?
Open source includes unlimited distribution. The game is still paid and they want to reserve distribution rights.
Open-source and source-available are used interchangeably. Releasing the source does not mean the license will allow any form of redistribution or recompilation.
If you decompile the game yourself you can infinitely distribute the game as well. This is not an argument.
Do you mean source available or actually open source?
I mean releasing the source under a license like GPL (or whatever the modern equivalent is).
I’d love to see that but realistically I don’t ever see it happening.
Because then anyone could fork it and redistribute the game which I presume they don’t want.
It would be sweet for us if they did, but I can see why they don’t want to do that.
Things like Minetest exist.
They could distribute source ports of the game, but you’d still have to buy the game in order to make use of them. Textures, sound effects, animations, etc. are (usually) not source code.
That’s why people still buy Doom 2 even though it was open-sourced in 1997.
Fork it and use your own texture and sound pack doesn’t sound like much work tbh. Any major modpack could just redistribute the game as a fork and it would be awesome. But Microsoft probably don’t want that.
The small amount of sales of doom 2 today is not at all comparable to the massive amount of minecraft sales and minecraft-related microtransactions that microsoft is raking in. Doom has many modern sequels that are far more popular today than doom 2, while minecraft does not have any official sequel.
I doubt that, but going source available is more likely imo.
Not only do I think this will generate a fair number of CVE’s, I think there will be a lot of optimization of the code going on.
Look at what happened with OpenOffice a few years back – the Oracle buyout of Sun Microsystems forced the forking of OpenOffice to LibreOffice – during which the new Dev team took the time cleanup and refactor the code. This resulted in a suite that was about 10 percent smaller, and removed a bunch of redundant things (like multiple copies of icons).
I bet we see something similar with Minecraft – even if it can’t be an “authorized” version.
This doesn’t really change too much for the modding scene, it just allows the deobfuscation step to be skipped when setting up a dev environment. Mojang has already been providing official deobfuscation mappings for years, and before that we had community-made ones which were already pretty great.
There are already plenty of mods which drastically overhaul how major parts of the game work to get better performance, and there are some projects like Gregtech: New Horizons and CleanroomMC which have pretty much completely torn apart and rebuilt the game on older versions from before official deobfuscation mappings were even available.
Right, but this means these efforts can be undertaken on the current release, and done without having to work around Mohjang’s obfuscation.
Removing this kind of barrier is a major change. Less time will be spent on trying to understand code that has been obscured from view. It will be easier to ensure “correctness” in code that is optimizing the server (ie, that new code will not break internal dependencies). It will be easier to ensure compatibility between the official release and community based extensions.
I understand that the modding community has been able to do a lot up to this point…(I play on an optimized modpack). But, I’m betting this will actually produce a larger jump in terms of the efficiency of all codebases - including Mohjangs. Just the reports that document issues (not CVE level issues) for Mohjang will lead to them improving the base code.
It has. There have been major rewrites of parts of the codebase, like Sodium, Cubic Chunk, server frameworks, just to start.
Major performance issues, and associated code fixes, have been repeatedly reported to Mojang’s tracker.
The issue is that any major modification is inherently incompatible with other major modifications, hence most persist for one version (or a few) before the devs burns out maintaining it. There are two solutions to this:
-
Get Mojang to pull in large optimizations. Thus far, they have been uninterested in this (though some controversy over Optifine may have left a bad taste).
-
Pull the changes into a modding framework. Understandably, Fabric/Forge aren’t willing to pull in a huge overhaul they’d have to maintain. Mojang may have similar feelings.
Some modifications (like Sodium) minimize vanilla changes to prioritize compatibility, and are popular to the extent that some other mods implement workarounds for them specifically. But this is rare, and it’s still problematic.
-
My point is that literally nobody has been looking at obfuscated code for at least 5 years by now. All the toolchains automatically handle de- and reobfuscation transparently to the point that nobody has to think about it anymore unless maybe you are one of the like 3 people who is actually maintaining the classloading stage of a modloader, or if you are manually writing a bytecode transformer (which almost nobody has needed to do for years either, ever since tools like Mixin entered the scene).
For 99.9% of the modding community, and this includes most optimization mods, the only thing that is going to change is everyone deletes a line or two from their
build.gradleand continues about their day.As far as reporting things to Mojang: again, nothing changes here either, everyone who has ever set up a mod dev environment already has a copy of the deobfuscated source code on their computer, which is the only thing they are looking at when inspecting the minecraft source code or making changes to it. There have been reports on the issue tracker with actual suggested code changes basically since the issue tracker became a thing.
I like to think that Luanti caused this.
Started experimenting with modding Luanti just last week. Was realy suprised how accesable and easy it is, even for an idiot with no experience like me!
Absolute cowards. Won’t even release the comments.
“No” - Bartosz Boq 2025
So, what’s the catch? Surely Microsoft and Mojang didn’t just suddenly become good?
Havent they been making changes to help mod/datapack development for a while?
Modding is such a big part of the game, helping it would get more people playing the game
They made “datapack” which is a way of playing with mods without having to use third-party mod loaders like Forge and Fabric but (don’t quote me on this as I’m not a mod developer) it’s not as powerful compare to the mod loaders.
Yup. Mods can change basically EVERYTHING, compared to datapacks being able to change only what mojang wants.
I guess it just doesn’t make sense to obfuscate it when mods in general runs the Minecraft community in turn making more profit to Mojang/Microsoft. My other suspicion is potential competition. There is this game called Vintage Story which kinda directly competes with Minecraft seems gaining ground and was built to be moddable from the start.
The monkeypaw says they will stop updates for the java edition or release a new version that doesn’t work on the java edition.
They probably see how many sales are generated from the free work done by modders though. If someone wants to come along and do for free the thing you might have to actually pay designers, developers, artists and all the support staff for and they still need to pay you to play it, you’d be foolish not to encourage the exploitation of free labor.
Young generations and mobile players are on bedrock
Everyone else plays Java where you can easily self-host a server
Call me ignorant, if this happened and it brought a new golden era of modding (1.7.10 style) where everyone’s playing the same version I’d be maybe the happiest player ever.
Modders backporting content is nothing new, hell, they even brought the mobs that didn’t make the cut from those stupid mob votes to life.
Let modding become the new updates, fuck it. At this point they’d likely be better realised than Microsoft’s efforts.Or a Bethesda style creation club is coming.
They already do that for bedrock.
Luanti eating on their turf.
Lol no
I doubt microsoft even knows what luanti is
Whats that?
It’s the platform that used to be MineTest, apparently
I said basically the same thing and got downvoted for it.
Hopefully the catch is nothing, but you can never be too sure.
I wonder how good AI is at deobfuscating code. It seems like the kind of thing it might be good at.
With how bad it is at writing it, I’m guessing similarly bad. It’ll do something, but odds are it introduces a ton of errors that you then have to track down. That’s the best case. Worst case, it just creates something totally different that looks similar to the input but doesn’t do the same thing.
I would advance: trying to keep the brand alive against the hidden giant of Roblox.
It’s a 20 year old game going into abandonware mode. This is the nicest way for them to do that.
-
Its 16, not 20, the earliest version “Cave Game Tech Test” was in May 2009.
-
They’re still actively pushing updates, a really big one is scheduled for the holiday season. Additional biomes and mini-bosses were added last year with structures hinting at development plans for a 4th dimension. The lighting engine is being actively redone.
Minecraft is absolutely not gearing down into abandonware mode.
And they finally added copper items 😂
-
Oh, wow. Just reading the title made me really excited about this.
I don’t really care what their incentive for this was, it’s a good move for the community.
This paired with the bedrock gdk release and changes to the file path so that we don’t need to use iobit unlocker to mod rtx files is some hella good vibes
I look forward to several critical CVE being discovered like log4j
Unironically, me too. They’re there now, waiting to be discovered. We can find them now on our terms or be surprised by them later.
Wasn’t log4j originally found by 2b2t players, then used maliciously and reported later on, then going onto get fixed by every major server framework like bukkit, paper, fabric, and more?
Nah, it was found sometime before november 24 2021, publicly disclosed in december 9 2021, and only used by 2b2t players on december 10 2021.
Can’t say I saw that coming, particularly after Microsoft bought them. Nice to have a surprise be pleasant once in a while.
The most profitable decision for MS is to leave the golden goose alone.
Oh I see it’s that time of the year where Mojang gives the community a bone after stomping on them the rest of the year.
Anyways as someone who has worked on Java projects extensively since 2020, very little will actually change from this. The main problem of Mojang’s asinine version numbering will continue to be a problem for any modding, server, building and resource pack projects past 1.19.
Mojang’s asinine version numbering
They do what now?
Previously, they had the versioning system 1.MAJOR.MINOR, where Major referred to a feature update, and minor referred to bug fixes or other non-breaking technical changes
The first instance where they broke this was 1.16.2 by adding the Piglin Brute, but this was so minor that hardly anyone really cared, and hey, free feature with a minor update!
Well, now they have update “drops” where the minor version means either what it used to, or it’s also a feature update, just not as big as a full update.
From the wiki:
- 1.20: Trails and Tales Update
- 1.20.3: Bats and Pots Drop
- 1.20.5: Armored Paws Drop
- 1.21: Tricky Trials Update
- 1.21.2: Bundles of Bravery Drop
- 1.21.4: The Garden Awakens Drop
- 1.21.5: Spring to Life Drop
- 1.21.6: Chase the Skies Drop
- 1.21.9: Copper Age Drop
That’s close to how the numbering system works! It’s MAJOR.MINOR.PATCH, Mojang just doesn’t use the major part at all.
Also I completely forgot the piglin brute existed! Also netherite templates got added it the 1.16 patch versions too if I am remembering right.
the problem is that the way version numbers are handled now, it’s more like 1.MAJOR.MINOR, with no real definition of what counts as a “minor” update, so it’s hard to tell which versions are compatible. i feel like this problem would mostly go away if they either added another number to the version to signify patches, or actually used semver properly (they could mix these approaches to do something similar to java, so the next version would be 22.0.0)
i feel like this whole version debacle is only gonna get worse because microsoft is planning to move to a “content drop” model, with smaller more frequent updates, which means even more pressure on the “patch” version. so unless their update model or versioning systen changes, we’ll probably be playing 1.21.37 in a couple of years, and good luck figuring out which of those versions are actually compatible
It’s kind of like Java itself, Sun dropped the leading 1 after 1.4, following it up with Java 5.
Mojang started adding in substantive resource pack changes in the patches for 1.19. Which made it more annoying for resource pack artists to support the update their since it required 2 separate versions of a pack to be made and maintained just to make sure it works properly. Let alone the annoyance of having to constantly deal with people complaining about it not working when it is an issue Mojang made.
There is also Mojang’s censorship of their community that began in the 1.19 patch versions which allowed Mojang to just ban anyone for saying something they didn’t like. Servers largely just disable it since it’s a headache to deal with and it doesn’t benefit them at all, only Mojang.
Then in 1.20 and 1.21 Mojang began adding content in the patches so it makes it a nightmare to support the patch versions since they now function differently than they used to. Which only makes it harder for servers to update and makes the experience of joining servers more frustrating. So plenty of servers on those updates just blacklist certain versions just to make sure things are able to function.
Oh and at some point Mojang added censorship to player skins. And it can be triggered by just mass reporting any individual skin for any reason.
Basically Mojang made a fuck ton of problems where none needed to be or used to be.
Also I just want to add this, but I was sounding the alarm on the patch version problem back in the 1.19 days. The community at the entire either ignored me or called me crazy for pointing out how it was problematic. Now the community is growing more and more annoyed and I’m just sitting over here saying I told you so.
I’ve mostly stopped playing the game because of Mojang’s constant shitty choices and because of the community refusing to call Mojang out on their bullshit.
The no chat reports mod and having community hosted servers that don’t really need to give a damn about what Mojang thinks (I’ll convert my server to support cracked accounts if I have to) kind of pulls the heavy lifting to allowing players to keep playing without having to give a shit about overall moderation by the company.
The no chat reports mod is great but it still is an uphill battle to get players to install it. We also need to focus on putting on Mojang to remove the problematic system in the first place so the experience is better for everyone including Bedrock players.
Installing the mod (or plugin) server-side strips all player chat messages of the information that makes them reportable, so no requirement is needed for the client (Although recommended for complete protection and for usage on non-compatible servers)
I am aware, all the servers I work on have it installed.
Fuckin right?
ALSO can Mojang get my goshfuckin ALPHA account back that Microsoft deleted because I wasn’t paying attention to their bullshit during COVID and now it’s gone forever even if I make a Microsoft account which I will never do and now I have to pay money to Microsoft (which I will also never do and have never done)?
I’m pretty sure it was promised to me that I’d have Minecraft access forever because I bought an alpha account, but I guess now I have to give point to a horrible soulless corp to buy it again.
