Does getting a stack trace for a thread have impact on its performance?

Question

Does getting a stack trace of a Java thread calling Thread.getStackTrace() have any impact on its performace?

EDIT: for monitoring purposes I would like to get stack traces of some monitored threads. I understand that parsing the stack of a thread could be a time consuming operation. In my case the most critical is that the performance of the thread for which the stack trace is being constructed is not affected.

from within the thread or from another thread? – Ron Jan 21 '12 at 00:07 — Ron, Jan 21 '12 at 00:07

Yes, there will be performance impact when you try to getStackTrace(). It need to back track stack dump of this thread. Here is interesting SO discussion on this topic.
