CFR - FAQ - yet another java decompiler.
Not for decompilation. I've written everything from scratch - partly because I'm doing this for fun, partly because I'm half tempted to port it to C++ at some point, so I don't want dependencies. There is a small reflective use of NIO, to allow the code to (still) require only Java6. ... CFR is very (very) deliberately java 6 only.

java - jar decompiler freezes on some jars (Tried Procyon, JD-cmd and CFR) - Stack Overflow

I received the jars you sent. I was able to decompile two of them successfully; the third jar (the smallest one) appears to be empty.

What version of Procyon are you using? On my workstation, both the latest release (v0.5.30) and the current development branch decompile the first two jars without hanging, though some classes do fail to decompile properly. Note, however, that both took a while to fully decompile: one took about 48 seconds, and the other took 2 minutes, 30 seconds on my 2013-era Core i7.

I did notice a few classes that might have taken a very long time to decompile with older versions of Procyon, back when there was a runaway complexity bug related to binary operators. Check your version number and grab the latest release if you're out of date.

On a side note, Procyon does not do a very good job with classes that have been run through tools like dex2jar. Even in the best cases, you should exercise a healthy level of skepticism toward any code produced by a decompiler. For code that has been transformed by dex2jar, you should be downright suspicious of the output.

To run the application, make sure you have Java 17+ installed and then simply execute the JAR file. To open an archive, select File > Open File (Ctrl + O) in the menu bar or directly drag and drop it. To change the decompiler, select the one you want to use, with the combo box in the top right corner. If you want to compare different decompilers side by side or decompile multiple archives at the same time, you can create a new instance from the menu bar File > New Instance (Ctrl + N).
