I submitted a patch for the demangling code in libiberty:

http://gcc.gnu.org/ml/gcc-patches/2001-01/msg02090.html

With this plus a recent cvs gdb, Java debugging seems to be working more
or less as well as it was under the old ABI.

It would be cool to implement JVMDI using ptrace(), bfd, etc, maybe write
a DWARF2 interpreter in Java. I estimate that would require roughly the
same effort as fixing the bugs in gdb would ;-). This would not be as
portable as GDB is, though.
