Performance issue because of the following thread in the production

Hi,
I am system administrator and am not aware of java and analysis the thread dump that is causing high CPU utilization in one of the production environment. I have implemented the script in linux environment to get the cpu wise thread report and found out the thread which is causing the issue. I have done some study in the google and seems like the issue with xalan jar file where we are using both the minor and majar version in the server [ xalan2.7.0.jar & xalan2.7.1.jar].
Please can someone help me in resolve this issue.

If you're having problems with Xalan, I suggest asking in a Xalan forum.

This is the bug tracker for the thread dump analyzer, and since it seems to be working fine for you I'll just close this ticket.
