Hello all,
I'm using commons-dbcp 1.4, and I found this exception. I don't if it's

So when I debugged it, it created a ManagedConnection, which is a sub-class of
DelegatingConnection, and the _conn is initialized with null, and the _closed
is false by default. So when hibernate calls the isClosed(), it throws a
nullpointer exception.
Could you guys tell me if in your side, or the hibernate side ?
Do not hesitate to contact me if you need more information.
