[kaffe] More Debugging woes

[Svante Arvedahl]

Hi Fabio,
What platform are you using? Are you using the jit? What I usually do (I
use the jit) is to debug with gdb and put a break point on soft_athrow
in soft.c. When the breakpoint is hit 'where' gives me the address in
the jitted code where the exception was thrown. Thru disassembling the
code and comparing with the java source code I can usually figure out
where I'm at.
