Comment 1 Damian Jansen 2014-07-28 05:57:44 UTC 
Tested 3.5.0-SNAPSHOT (git-server-3.4.2-201-ge0afdde) - no longer an issue
Comment 2 Sean Flanigan 2015-04-17 03:44:19 UTC 
I suspect this may have been caused by the accidental use of MyISAM for some tables.
Comment 3 Sean Flanigan 2015-04-17 06:38:30 UTC 
On second thought, I have been seeing StaleObjectStateException in functional tests, which are probably not using MyISAM (MySQL 5.5.34 should default to InnoDB).  I think MyISAM problems must manifest differently.


org.zanata.feature.concurrentedit.ConcurrentAccessTest sometimes triggers these exceptions, especially if you run a few copies at once.

It's looking very much like a thread safety problem.  I'll see what I can do, at least for ConcurrentAccessTest.
