unwinding java frame

Hi Sagar,
If you're running on a debug build (fastdebug/jvmg) of HotSpot, from gdb you
could invoke helper functions defined in src/share/vm/utilities/debug.cpp to
gain easier access to HotSpot's internal data structures.
Specifically,
to print the stack trace of the current thread, use ps();
to print the stack trace of all thread, use pss();
I've attached an example at the end of this email.
There are of course other ways of doing it in gdb, that may or may not
require
a debug build.
Instead of gdb, I use SA-based (Serviceability Agent) tools more often,
e.g. jstack -m. It works on live Java processes and core dumps, and doesn't
require a debug build of HotSpot.
Hope it helps,
- Kris
Example:
Start a Groovy shell, and then attach gdb onto it:
kmo at ubuntu:~
$ jps
24548 Jps
24514 GroovyStarter
kmo at ubuntu:~
$ sudo gdb

(Note: the ps() function, and a couple others, expects the "current
thread" to be a Java thread.
Be sure to switch the thread to a Java thread before invoking them in
gdb, otherwise you'll crash the debuggee process.
In this example, I switched to thread 18 first, which is the "main" Java
thread.)
You may be wondering where the result of ps() went, well, here it is:
