Comment 2 Tomas Zezula 2011-01-27 12:43:11 UTC 
beingIndexed is probably null, not related to Lucene 3.0
I will debug it.
Comment 3 Tomas Zezula 2011-01-27 14:43:07 UTC 
I am not able to reproduce it :-(
But if I understand it correctly it's a race condition.
The indexLoadedRepo is guarded by write lock which is allocated per repository. But the NotifyIndexCreator.beingIndexed is static shared among all instances. When one loading completes it can overwrite the value by null.
Making it instance variables (if more progress should be displayed at once) should solve it.
