jd-gui VS vineflower

You need something like this: https://github.com/java-decompiler/jd-gui

Try opening it with jd-gui first

Googling shows me a bit of issues related to JD-GUI having some issues with decompiling Enums. One such issue. I would recommend using a more reliable product if this is something that you have to do. IntelliJ has a built in decompiler which is FernFlower. So you could try that route and see if you get the same issue.

With an open source, client sided Java app you can always use a decompiler on the jar file and verify exactly how your file is handled. And that way you can verify (if you know java) that the session ids are never extracted or sent to anyone.

i’d say this is a good program for decompiling java stuff

The desktop file mentioned seems to be this: https://github.com/java-decompiler/jd-gui/blob/master/src/linux/resources/jd-gui.desktop

Decompiler for jars called Java Decompiler, has a lil gui (cmd line version available): https://github.com/java-decompiler/jd-gui

If you need to inspect the source code, try this https://github.com/java-decompiler/jd-gui

this is kind of a silly point, but the quilt community is just nicer to be around than any of the other ones in my experience, which has real effects: e.g., you attract people really really good at decompiler tech and create quiltflower which is a decompiler so good Java professionals use it. inclusivity matters! the cutting edge happens on quilt

The only way is to reverse-engineer it. Use something like quiltflower or javap if you want to be extra sure, and have a look through the Java code

Firstly, we have to decompile the JAR, turning the bytecode back into Java. This is a very difficult job: a lot of work has been put into the tools to make this happen.

Alternatively, there's this new project that I haven't tried yet: https://github.com/QuiltMC/quiltflower

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.

They are community contributed (through using decompilers to see what the classes do) and decompiler toolchains have ways of instrumenting classes with javadoc. They are also incomplete, you really can't write a mod using only a javadocs page

runs nice with jbang https://github.com/QuiltMC/quiltflower/releases/download/1.8.1/quiltflower-1.8.1.jar
