Hi,

Not sure. Bug described in bug tracker does produce "local
transaction is active" message. In fact there is no message related
to this bug, only incorrect behavior when closing connection. Managed
connection factory notices that there is an active transaction
associated with database handle and does not release it, however
managed connection assumes that transaction was ended and handle was
released. This resuls in a lost database handle (and socket).

However I haven't fixed it, but assigned bug to David, because I'm
afraid to break something in JCA stuff.

Best regards,
Roman
