Comment 2 J Bachorik 2012-04-18 14:10:39 UTC 
Seems like you have tried to obtain a profiler snapshot before terminating the session. Can you provide some steps to reproduce?
Comment 3 akochnev 2012-04-18 15:41:21 UTC 
I don't have any further steps to reproduce. Even if I did something unexpected/invalid (e.g. tried obtaining a snapshot before terminating the session) it seems that at least the exception should be handled more gracefully
Comment 4 J Bachorik 2012-04-18 17:41:43 UTC 
Actually, the exception is caught and logged. But the Level.SEVERE seems to force the IDE to display the exception dialogue.
It would be the best to find how to prevent the exception but for the time being we might log it just as a warning instead (will go to the log but will not be shown to the end user)
