Description Andrew Overholt CLA 2010-06-17 16:51:16 EDT 
I opened the 3 SystemTap perspectives and later closed Eclipse.  In the terminal from which I launched Eclipse, I saw:

Exception in thread "TapsetParser" java.lang.NullPointerException

Various fixes went in which correct the shutting down of TapsetParser and generally improve the way it works. This should be fixed now. Please reopen if this NPE appears again.
