On Mac OSX 10.6 suites.All fails with Exception in thread "main" java.lang.OutOfMemoryError:
PermGen space even with -XX:MaxPermSize=128M
-----------------------------------------------------------------------------------------------------------------------------------------

                 Key: DERBY-4740
                 URL: https://issues.apache.org/jira/browse/DERBY-4740
             Project: Derby
          Issue Type: Bug
         Environment: Mac OS X 10.6 

java version "1.6.0_20"
Java(TM) SE Runtime Environment (build 1.6.0_20-b02-279-10M3065)
Java HotSpot(TM) 64-Bit Server VM (build 16.3-b01-279, mixed mode)

            Reporter: Kathey Marsden


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.
