Recaf VS JByteMod-Beta

IF you've got the legal situation all sorted out, and know that you need to change a Java class file, and know how to program in Java, I'd suggest Recaf. With it, you can import a jar file, decompile, edit and recompile any source files in it, and export the whole thing again.

No one seems to mention Recaf wich is the best option IMO. You can choose between different decompilers (Fernflower, CFR, Jadx, Procyon and others) has bytecode editing capabilities (you don't have to fully decompile, you can edit the bytecode directly), built in peephole optimizations for flow and number obfuscations, various search options for methods, members, strings, and method virtualization via SSVM

Uhhh, no? For something like JavaFX, which I've complained about its bad native handling before, you can still make a multi-platform jar with a little bit of effort. For instance my project Recaf is distributed as a single JAR file. Just install JDK 11+ and you're good to go.

I did something like this, but its not its own control/library: https://github.com/Col-E/Recaf/blob/dev3/recaf-ui/src/main/java/me/coley/recaf/ui/pane/DiffViewPane.java

The decompiler they used to view that code is not very good, that output is garbled.

If you're going to take apart JVM bytecode, you're better off using Recafe or Quiltflower.

I've recently been searching for tools that can help me find rats within jar files. So far I've found jd-gui and Recaf, do you all have any suggestions for other tools?

Example: DecompilePane.java

First go grab JByteMod from their GitHub https://github.com/GraxCode/JByteMod-Beta/releases Download the latest zip version (currently JByteMod-1.8.2.zip) and unzip the contents to somewhere on your computer. Run the JByteMod-1.8.2.jar you just unzipped. (You need a Java RTE of your choice) Menu File > Load > Select your server jar file Menu Search > Search LDC > Find "www" Go to the Search tab to see the results and find the line with: "http://www.minecraft.net/game/checkserver.jsp?user=" Right click on it > "Jump to Declaration" Now you should see the bytecode listed in the Editor tab. Find the line again and left click on it. Then right click > Edit Change "www" to "session" and click OK Menu File > Save as > save it as a jar file with a new name eg "Server_online.jar" Replace your existing server jar with the new edited online jar in your server and edit your server.properties file to have online-mode=true instead of false. Done!
