Hi,
Please review this fix for bug 6310967 <http://bugs.sun.com/bugdatabase/view_bug.do?bug_id=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
