Mamta A. Satoor commented on DERBY-3404:
----------------------------------------
BTW, the reason for locking problems without the changes into testXADataSource
test is that the test failed because it didn't get the SQL State it was
expecting but as a result of failure, the locks held by the test remained on
the tables and later, when we go through the tear down process and try to drop
the tables, we ran into locking issues.
In any case, this issue of locking is not more a problem because I have changed
the testXADataSource in 10.3 codeline.
As i said earlier, I will soon merge the changes into 10.3 and then close this
issue.

> Key: DERBY-3404

> Project: Derby
> Issue Type: Bug
> Affects Versions: 10.3.1.4, 10.3.2.1, 10.4.0.0
> Reporter: Knut Anders Hatlen
> Assignee: Knut Anders Hatlen
> Priority: Minor
> Fix For: 10.4.0.0

> Attachments: CloseOnCommit.java, d3404-v1.diff, d3404-v1.stat

> The following code prints "null" to the console with the embedded driver:
> Statement s = c.createStatement(ResultSet.TYPE_FORWARD_ONLY,
> ResultSet.CONCUR_READ_ONLY,
> ResultSet.CLOSE_CURSORS_AT_COMMIT);
> ResultSet rs = s.executeQuery("select * from sysibm.sysdummy1");
> rs.next();
> c.createStatement().executeQuery("values 1").close(); // causes
> auto-commit
> System.out.println(rs.getString(1));
> The call to rs.getString() should perhaps have thrown SQLException, since the
> auto-commit between next() and getString() should close the ResultSet when
> the holdability is CLOSE_CURSORS_AT_COMMIT, I think. Anyway, the value stored
> in SYSIBM.SYSDUMMY1 is 'Y' and not NULL, so it should definitely not return
> null.
