Thanks for the info.

I'd prefer to handle the Java stuff instead of ignore it.  It should
only take an hour or two of work: it's pretty clean, so it should just
involve adding one simple variant of struct environment and futzing
with symtab.free_ptr slightly.  (Which seems to currently only be used
in this specific situation, admittedly a bit of a space waste...)

Certainly if I were looking for pieces of code to ignore over the
course of this process, mdebugread.c would be a much higher priority
for me...
