Can I Debug jvm "core" dump file?

One of our J2EE program crashed periodly, and some core files were
generated.

In the core dump file, shows memcpy triggers "Unexpected Signal 11"
error. This happens consistantly. But that only shows assembly, and I
believe the final fail point is in C library.

Just wondering whether there is some tools, like JProbe, to read the
core file, and show the stack trace up to java class level?

Thanks
