----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------
Key: DERBY-5440
URL: https://issues.apache.org/jira/browse/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
Priority: Trivial
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.
