I'm happy if you find them clear as they are really concise. Only 3

I noticed an error in these instructions as zips do not contain sources
of the flex-compiler.jar. Sources are in
intellij-plugins/flex/tools/BuiltInFlexCompiler and subfolders. I'll fix
readme. There's a project (.idea folder) configured in this folder but
it is not ready to use out-of-the-box. I didn't write any instructions
for it yet, I didn't adapt it for external contributors and didn't
update it for several years. You may try to base on it or configure your
own new project that would contain all sources from this folder.

I hope I can.
You have control on the Java process startup
(JpsBuiltInFlexCompilerHandler.startCompilerProcess()), you have source
code (intellij-plugins/flex/tools/BuiltInFlexCompiler), you have an IDE
that can debug and you know how Java debugger establishes connection.
That's all you need to debug. May be I'll find time to preconfigure a
project and to write detailed steps, but I hope you'll be able to set up
without waiting for it.
