---------------------------------

Thanks Gary!
Is there an estimate when a version of DBCP will be released with this fix?

> 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.
