Hi Amos,
I did something like this with the JarSigner code in order to reverse
engineer it in C, which in the end I was able to do. IMHO, gdb is too high
a granularity to get anything usable out of the JVM execution. I suspect
that there is no alternative to sowing System.out.print's throughout the
code.

Subject: Looking for directions about compiling and tracing OpenJDK
Hi,
I have an idea which involves going somewhat deep into the bowls of the Java
Jar class loader when using the official Oracle JDK 6 (and soon 7).
To verify this I started looking at the JDK source code but it's not small and
I'd like to try to trace through it while it executes Java programs.
Does anyone here have experience in doing something like this and can give me
some useful pointers on how to do this?
I'd like to be able to do "gdb java -jar HelloWorld.jar" and single-step
through the class loader while it loads HelloWorld.jar.
Thanks,
--Amos
