I should further point out that this language feature does not create the need for a wrapper. You should have the wrapper already, unless of course you enjoy writing the same rollback/close logic over and over. Connection wrappers are also already necessary for other reasons: http://weblogs.java.net/blog/crazybob/archive/2004/03/ patchleakycon.html Bob

They certainly are. After putting a system live a couple of years
ago we found that the VM was mysteriously switching timezone part way
through the day. Turned out to be the JDBC driver changing the
timezone to do a calculation, then changing it back. Apart from
being an incredible hack, it was also completely unsynchronized, so
when the system was under load one thread would change it, then
another would store the changed value as the one it should restore it
to, after which the VM was permanently in the other timezone.
