Description Andrew Overholt CLA 2010-06-07 09:39:42 EDT 
After verifying some other SystemTap bugs, I noticed this in my terminal.  At a minimum I'd like to see this go to the consolelog instead of the console.

Exception in thread "TapsetParser" java.lang.NullPointerException

Roland/Charley, if you have a second, can you help Anithra out by seeing if you can reproduce this?  If you can't reproduce it, close it, as I may have been experiencing issues with my installation at the time.  Thanks.

Hides the message

I think this exception might occur when systemtap is not installed on the machine, this will need to be reopened and investigated later.

This doesn't reproduce for me either. I believe the error is caused by viewer being null -- I can get the update event to fire but the viewer variable is never null for me. Tried removing some tapsets from the tapsets folder as well.

I've opened all the SystemTap views and perspectives that there are and I can't reproduce this with the latest build (#234, 201006081201).  Thanks.
