Random Invalid Session Errors in Netcool WebGUI

I am trying to work in Netcool WebGUI and it randomly logs me out with a session invalid error.

Error message: "Your session has become invalid. This is due to a session timeout or an administrator has logged you out"

I then log back in and get the same error twice before it finally lets me back in.

This was found to be while doing anything java related. This included TBSM, Filter Builder, Maps, Active Event List (AEL) and other java related pages.

We found the issue to be Java. Java Runtime Environment (JRE) version 6 update 29 (1.6.0_29) on the local machine running WebGUI client will cause this problem.

The fix: upgrade to Java Runtime Environment (JRE) version 6 update 30 (1.6.0_30) or better.
