Debug jdk asserts as follows:
(more details on debug jdk asserts, core, stack, showrev, uname, etc in attached
file: /afc_crash_javag_1016.tar.gz)
*** panic: "../../../../src/share/javavm/runtime/stackwalk.c", line 287: assertion failure (recursive):
expression: (old_pc == ((void*)2)) || (csw->cFrame == 0) || (old_frame < ((uintptr_t)(csw->cFrame)))
first failure: "../../../../src/share/javavm/compilers/compiler.c", line 1237:
expression: ret == FALSE

Unfortunatley, the above asserts happen consistently during application startup and
not during application testing phase. Perhaps this is just the debug jdk asserts
being more strict, and not related to the actual jdk SIGBUS crash.


We have also seen a somewhat similar jdk crash on the same system, the stack for
which is as follows:
