Dag H. Wanvik commented on DERBY-6422:
--------------------------------------
It's not obvious to me this is a Derby problem: Hibernate seems to be calling
"getAutoCommit" [1] on a closed Derby connection. It could, of course, be that
Derby has experiences a problem and so erroneously closed the connection
without throwing any indication to Hibernate, but this should be investigated
first. Any clues in derby.log

> After running performance code for long time, suddenly no connections are
> available
