Currently, there are most of java decompilers, but all of them use their own editors to view the decompiled source code, and most of them couldn't highlight the java key words.

What's the advantage of JDecompiler?
It is very small, and very fast to run.
It can use your favorite text editor (e.g:EditPlus, UltraEdit etc) to decompile and view the java class file! Yeah, that's amazing.
It can add the original line numbers as the comments in the decompiled file, that is very useful for debugging.
It is simply to use, you only need to specify your favorite text editor firstly. Then you can double click a .class file from the Explorer or a jar(zip) file freely. It will automatically start your favorite text editor to decompile the .class file and view the decompiled source code.
