How to identify what started a Thread [duplicate]

Question

Possible Duplicate:
Can I get the name of the class and method within which the current thread was spawned?

Are there any tools (perhaps a javaagent) that will let me identify what started a thread after the event?

I have a Tomcat that won't shut down, and the thread names (from the dump) aren't of much use.

I was going to say it is not duplicate because OP wants to know this after the fact. Then I realized the OP wants to close it:) — Miserable Variable

The lowest level call of a stack trace might indicate how/why a thread was started...

Do one thing, print the stack trace, and you will get who started the thread.

You don't have to print it. It's available from a getter: Thread.currentThread().getStackTrace() since 1.5

Does tomcat do something special here? Otherwise, the stacktrace stops at Thread.run

I already have the stack trace (hence my comment saying I had the dump) but that doesn't give any useful information.
