Hi. The NullPointerException seems to be an ugly
simple bug in the Oracle thin driver you're using,
but it might have been triggered by a lower-level
connectivity problem that also caused your rollback
to fail.
I would update your thin driver to the latest 10G one,
and in the case of a failed rollback, it hinges on whether
this is a simple local tx or an XA tx. Xa has a recovery
protocol that tries to determine the status of the tx
after a reconnect is made. A non-XA tx leaves it up to
you to reconnect (I'm guessing the connection is dead),
and see if what you tried to do and then rollback succeeded
or not. Most DBMSes will roll back any abandoned transactional
content on a connection that goes away without explicitly
committing, but Oracle is different, and *will* commit sometimes.
