> Key: DERBY-5440

> Project: Derby
> Issue Type: Bug
> Components: Test
> Affects Versions: 10.8.2.1
> Environment: IBM iseries 6.1, Classic 1.6 JVM
> Reporter: Myrna van Lunteren
> Assignee: Knut Anders Hatlen
> Priority: Trivial
> Attachments: d5440.diff

> During the QA Cycle for 10.8.2.1 I also ran on a next version of the iseries OS, and saw this failure. It did not reproduce when I reran the test by itself. The test has the following comment:
> // Give the other thread time to obtain the lock
> Thread.sleep(1000);
> // Perform an index scan. Will be blocked for a while when fetching
> // the row where x=100, but should be able to resume the scan.
> ResultSet rs = s.executeQuery(
> "select * from t --DERBY-PROPERTIES index=IDX");
> for (int i = 0; i < 300; i++) {
> assertTrue(rs.next());
> assertEquals(i, rs.getInt(1)); <==== this is the line of the failure.
> }
> I think this is a rather slow machine, and that's likely why I saw the failure, perhaps the sleep wasn't long enough on this machine.
