Yes, I did run with -Xint and JVM crashed. With out -Xint, the program
was just not be able to run.
They had different error messages.

Thank you for your suggestion. LDC to load an ASM Type is just great.

You have good eyes ;-) It's Andrei Loskutov's Bytecode Outline plugin

You use an agent? Does this mean I can just run my code unmodified?
I will try it and let you know.
