jstack

[Anders Nordby]

Hi!

This is an old email, but I figured I would answer and give my comments
anyway.

I agree very much that tools like jmap/jstack would be very handy when
debugging Java programs. I hope the Java porters one day would fix it.
:-)

In the mean time, I just discovered that you can get a thread dump by
sending SIGQUIT (kill -3 <pid>) to a running Java process. This output
can be analyzed by IBMs jva, http://www.alphaworks.ibm.com/tech/jca. At
least I was told it should work on analyzing data from Sun based JDKs
also.

Let me know if this was useful to anyone.

Thanks and regards,
Anders.
