> If you call close on a logical connection, for instance as obtained through a PooledConnection, it does not check if there is an active transaction.
> The close of the logical connection is allowed, and even the close of the parent PooledConnection is allowed in the client driver. This can/will cause resources to be left on the server, and later operations might fail (typically with lock timeouts because the "closed" transaction is still holding locks).
> I do not know if gc will solve this eventually, but I would say the current behavior of the client driver is wrong in any case.
> There is difference in the behavior between the embedded and the client driver, and there also seems to be a bug in the embedded driver.
> The analysis above is a bit sketchy, so it might be required to look into the issue a bit more...
> I will attach a repro (JDBC usage should be verified as well, is it legal / as intended?)
