> Affects Versions: 4.4.CR1
> Environment: Standalone JTA build
> Reporter: Michael Musgrove

> Use the Transactional Driver to get a JDBC connection (this returns a ConnectionImple which wraps the connection to the real resource and enlists/delists it with transactions). After running about 500 transactions the underlying resource throws an error reporting "Too many connections" (I tried this on Derby and MySql XA drivers).
>
> The real connection is implemented by RecoverableXAConnection - when a transaction completes the reference to the real connection is nulled (and therefore not closed) so on the next transaction a new connection is obtained so the resource manager eventually runs out of connections.
