NullPointerException during concurrency tests?

Got this while running two threads (in seperate processes) searching and updating DS:

Should I just log in JIRA?

Yeah that's a good idea but please put some more info about your 
environment.  The version of ADS your using etc.  And a test case that 
captures the situation so we can reproduce this bug would also help too.

Otherwise I'm afraid this class of problem is so tricky that it may 
elude us.
