Hi Vivian,

You are probably also the victim of the double close issue
http://issues.apache.org/bugzilla/show_bug.cgi?id=22079
and/or the race condition (16987).

Your problem should be solved by using a nightly build.
But you will probably get some SQLException: Already closed. Using these
exceptions you can find the root cause: the double close.

If you find that a nightly build solves your problem let us know then we
can start thinking about releasing a new version.

Cheers
Dirk
