+ == Mac , Oracle and HP JVM's MaxPermSize ==
+ On  Mac, Oracle and HP JVM's  it is necessary to set -XX:MaxPermSize=512m (or possibly as low as 128m in some contexts)  in order for the upgrade tests to complete.  This option increases the class loading space so that the upgrade tests can load the various versions. It may be that this is a bug with upgrade tests or even Derby that class loaders are leaking [[https://issues.apache.org/jira/browse/DERBY-4740| DERBY-4740]].  The IBM JVM's do not have a separate option for the class definition loading. It is combined with the heap so this option is not needed.

  == IBM WEME 6.1 Foundation (windows with -jcl:foun11) ==
  
  A newer version of WCTME 5.7.
