GDB's java support is quite broken right now. Here's an example...
(gdb) set lang java
(gdb) ptype jmisc
type = class jmisc extends java.lang.Object {
void main__5jmisc_ZN5jmisc4mainEP6JArrayIPN4java4lang6StringEE;
void _ZN5jmiscC1Ev;
}
The stabs data refers to this correctly mangled symbol...
_ZN5jmisc4mainEP6JArrayIPN4java4lang6StringEE
So how does the physname get the "main__5jmisc" prefix? The full
main__5jmisc_ZN5jmisc4mainEP6JArrayIPN4java4lang6StringEE string is
passed to the v3 demangler, which doesn't recognize it and assumes it
is a C symbol.
Any ideas?
Thanks,
AG

From the fun way we extract type info off of methods, in STABS, of
course!
breakpoint on parse_and_eval_type or something like that, and you'll see
it happen.
