------------------------------------
Alan, thanks for checking. I hadn't gotten around to look at the test results
in detail.

> Here is related code:
> {code}
> Connection conn = null;
> boolean committed = false;
> try {
> conn = getConnection();
> ...
> } finally {
> if (!committed) conn.rollback();
> conn.close();
> }
> {code}
> If getConnection() throws exception, conn.rollback() would be called -
> leading to NPE.
