Description Andrew Overholt CLA 2011-05-27 16:09:24 EDT 
While testing out the SystemTap plugins in the latest Indigo build, I got the following NPE in my workspace/.metadata/.log:

Comment 1 Andrew Overholt CLA 2011-05-27 16:09:48 EDT 
Please fix this for 0.8 (ie. ASAP :).
Comment 2 Andrew Overholt CLA 2011-06-03 16:32:22 EDT 
This is not easy to reproduce so let's punt it to post-0.8.
Comment 3 Alexander Kurtakov CLA 2013-01-18 17:01:36 EST 
I would close this one as a number of things changed since it was opened and there are no steps to reproduce nor I've seen it.
Please reopen if you can reproduce and give us exact steps to do it.
