Description ehucka 2006-08-09 11:54:20 UTC 
It is not easy to reproduce.
It usually occures when I invoke take snapshot and than stop profiling.

Comment 5 J Bachorik 2006-09-13 13:34:56 UTC 
This is the result of a race condition. The array of class names is being
expanded  and displayed in parallel. If the newly created member of the array is
accessed before it's initialized with the class name the NPE is thrown. 
Now the access and modification is being synchronized so the UI part should have
access only to completely initialized class names array.
