Comment 3 Alexander Kouznetsov 2007-09-25 13:44:39 UTC 
The same result when snapshot is opened from Saved Snapshots list.
Comment 4 J Bachorik 2007-09-26 10:33:23 UTC 
the main reason is that a completely empty snapshot was taken - the fix should correct the way such a snapshot is
handled and also prevent the triggered PP to generate a completely empty snapshot
Comment 5 J Bachorik 2007-10-01 12:30:16 UTC 
there were also additional problems with inconsistency between the number of instrumented classes and the number of
class names stored in the snapshot
this is resolved, hopefully, by improving thread safety while taking snapshot
Comment 6 Alexander Kouznetsov 2007-10-31 18:50:40 UTC 
Filed another issue 120696 about the unavailability of data for Triggered PP Snapshot.
