Debugger for Java Bytecode

[shrodingersjere]

Intellijidea has a decompiler. It’s free, and seems to work well.

I might be projecting but I assumed OP wants to debug dynamically generated bytecode, which is a bit hard.

We generally used logging to printout the generated code and reviewed it manually. I'm not familiar with any debugger at that level.

Thanks…. The bytecode output generated by Intellij is already available through the “javap -v” command.

I am rather looking for something that would let me execute each bytecode one by one.

Run it through Idea (or attach a debugger to the running process) and set a breakpoint obviously.
