Shut down engine for old versions in upgrade tests to save memory
-----------------------------------------------------------------

                 Key: DERBY-5267
                 URL: https://issues.apache.org/jira/browse/DERBY-5267
             Project: Derby
          Issue Type: Improvement
          Components: Test
    Affects Versions: 10.9.0.0
            Reporter: Knut Anders Hatlen
            Assignee: Knut Anders Hatlen
            Priority: Minor


The memory requirements for the upgrade tests seem to go up each time we add a new release.
Lately, they've started failing on phoneME with the error message saying "Number of class
names exceeds vm limit." It looks to me as if the problem is that we don't shut down the engine
when we've finished testing a version, so we eventually end up with 19 different versions
of the engine loaded in the same process. I think it would be good to shut down the old engines
when we're done with them to free up resources.
