Description

Seen with svn r805448 on tinderbox/trunk ( http://dbtg.foundry.sun.com/derby/test/tinderbox_trunk16/jvm1.6/testing/Limited/index.html ).

See e.g.

http://dbtg.foundry.sun.com/derby/test/Daily/jvm1.6/testing/Limited/testSummary-805470.html .

The failure signature is

This seems to be a similar failure signature as for DERBY-3561 and DERBY-3499. I choose to create a new issue for the new occurrences.
