>>>Well you probably already know this, but a few weeks ago I added 
libjava/sysdep/dwarf2-backtrace.cc which as its name implies generates a 
backtrace via the libgcc unwinder. However as was noted earlier, this 
is of little use when the eh_frame info is not available.
It seems to me that if there is no other way to get a backtrace than 
using -fno-omit-framepointer and walking the stack, then that is what 
you have to do.
The alternative is to not be able to get a stack trace, which implies 
that much of the java security infrastructure will not work.
