Hi Poonam,
It seems to me that rather than passing the ThreadProxy through to
f.sender the frame, which has to be a frame of some thread, should
already know what that thread is and so be able to access it directly.
In other words: shouldn't each CFrame maintain a reference to the thread
it corresponds to?

Hi,
Please review this fix for bug 6310967

6310967 <http://bugs.sun.com/bugdatabase/view_bug.do?bug_id=6310967>:
SA: jstack -m produce failures in output
http://cr.openjdk.java.net/~poonam/6310967/webrev.00/
Problem: jstack -m fails with UnalignedAddressException.The problem is
that while finding the caller frame of a frame in sender() method, we
don't check the validity of the frame pointer (rbp / ebp).
These changes add a simple check that the frame pointer(rbp) should be a
valid pointer on the stack by making sure that it is not less than the
stack
pointer(rsp).
Thanks,
Poonam
