Knut Anders Hatlen updated DERBY-3422:
--------------------------------------
Attachment: d3422.stat
d3422.diff
Attached is a patch that changes the return value for
EmbedDatabaseMetadata40.autoCommitFailureClosesAllResultSets() and updates
TestDbMetaData.
When this patch is applied, autoCommitFailureClosesAllResultSets() returns
different values on embedded and on the client, so if the approach is accepted
and the patch is committed, we should also file an issue to track the
difference between client and embedded.

> DatabaseMetaData.autoCommitFailureClosesAllResultSets() returns false both on
> the client and on embedded. However, the embedded driver does in fact close
> all open result sets when an error occurs in auto-commit mode. There is a
> test case in jdbc4.TestDbMetaData to test this (testAutoCommitFailure), but
> it only uses ResultSet.isClosed() to check whether or not the result set is
> closed after the failure. Because of DERBY-3404, isClosed() returns false for
> the result sets that have been closed because of the failure, so the test
> doesn't reveal the bug. If the test is changed to invoke methods on the
> result set (e.g. next()) instead of calling isClosed(), we'll see that the
> result set is in fact closed and get an SQLException with SQL state XCL16.
