      Description

      On Mac OS X 10.6 I ran suites.All with:

      java -Dderby.tests.trace=true -XX:MaxPermSize=128M -Xmx1024M -Xms512M -DderbyTesting.oldReleasePath=/Users/kmarsden/Derby/svn/svnreleases/jars junit.textui.TestRunner org.apache.derbyTesting.functionTests.suites.All 2>&1 | tee rjall.out

      It failed in the upgrade tests with:
      testDMDconnClosed used 9 ms Test upgrade done.
      Test upgrade from: 10.2.2.0, phase: POST UPGRADE
      .
      noConnectionAfterHardUpgrade used 4 ms Test upgrade done.
      Test upgrade from: 10.3.1.4, phase: CREATE
      Exception in thread "main" java.lang.OutOfMemoryError: PermGen space

      I was able to work around the issue by setting -XX:MaxPermSize=256M but think perhaps the upgrade tests may be leaking class loaders.
      PhaseChanger.teardown() is careful to shutdown each database but not the Derby system, so it could be the class loaders are not getting garbage collected.
