Custom ReverseEngineeringStrategy class not loaded in Eclipse 3.4 Ganymede when project uses JDK 6
--------------------------------------------------------------------------------------------------

                 Key: HBX-1088
                 URL: http://opensource.atlassian.com/projects/hibernate/browse/HBX-1088
             Project: Hibernate Tools
          Issue Type: Bug
          Components: reverse-engineer
    Affects Versions: 3.2.2
         Environment: Hibernate Tools 3.2.2 Nightly from 9/10/2008 
OSX Leopard 10.5.4
Eclipse 3.4 Ganymede
Eclipse Project: WTP 3.0 EJB Project, set to use Java 6
Java 1.6.0_05-b13-52 64bit (Mac OSX)
MySQl 5.1.26 
            Reporter: Rich Taylor
            Priority: Minor


When trying to execute a hibernate tools generation in Eclipse Ganymede with a custom ReverseEngineeringStrategy class, the class cannot be found by hibernate tools.   I only get this error when the project is set to use JDK 6.  If I lower it to JDK 5 the issue goes away.    Here is the resulting stack trace when executing the generation:
