Bruce Schuchardt commented on GEODE-6812:
-----------------------------------------
I looked at this dunit failure and it doesn't look the same as GEODE-6823 to
me. That bug will always result in a hang. The NPE is probably due to some
other flaw in the refactored Elder management code. To me it looks like
getElderState() might have faulty code. For instance, it calls waitForElder()
without checking the return value, which could be false during shutdown. In
the failed run vm5 was shutting down when the NPE was thrown.
