Kathey Marsden commented on DERBY-3319:
---------------------------------------
I raised the priority of DERBY-1191 for the general case and linked it to this
issue. I think this particular case is pretty urgent as it seems really hard
to track these issues down as we found in DERBY-4053 and DERBY-4225 but I don't
know if it is easier just to fix the general case. If not a subtask of
DERBY-1191 can be filed to fix this one.
> Logical connections do not check if a transaction is active on close

> Key: DERBY-3319
> URL: https://issues.apache.org/jira/browse/DERBY-3319
> Project: Derby
> Issue Type: Bug
> Components: JDBC, Network Client
> Affects Versions: 10.3.2.1, 10.4.1.3, 10.5.1.1
> Environment: Embedded driver and client driver.
> Reporter: Kristian Waagan
> Assignee: Knut Anders Hatlen
> Fix For: 10.5.1.1

> Attachments: d3319-1a.diff, d3319-1a.stat,

>
> 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?)
