John Hendrikx commented on DERBY-5545:
--------------------------------------
I've got this too, and I tracked it down to a query within a savepoint.
I'm using the embedded driver, and basically the sequence of events that is
causing this is:
Sequence of events
Connection created
query executed, resultSet obtained (1 record)
rs.next()
--savepoint set
--query executed, resulSet obtained (1 record)
--savepoint rollback
rs.next() -> exception (I would expect false to be returned).
Now, I can reproduce this every single time. If I change the savepoint
rollback to a releaseSavepoint then it works. This must be a bug I think?
> Exception ResultSet not open. Operation 'next' not permitted. Verify that
> autocommit is OFF exception occuring on rs.next() after long run.

> Project: Derby
> Issue Type: Bug
> Components: JDBC
> Affects Versions: 10.8.2.2
> Environment: OSX 10.6
> Reporter: Paul taylor
> Labels: derby_triage10_9
>
> Im seeing this error occur after loading alot of data into the Database. I
> can confirm that autocommit is set to off, and that it occurs on calling
> rs.next() immediatlely after running a query and assigning to resultset rs.
> The cdoe is called many times (250,000) and usually works, then suddenly it
> starts going wrong, I also using c3po database pooling. Im wondering if the
> problem is linked to memory consumption although I have no OutOfMemoryError
> occurring
>
> Java.sql.SQLException: ResultSet not open. Operation 'next' not permitted.
> Verify that autocommit is OFF.
