NotAuditedException occurs when auditReader.getRevisions() is called for javassist proxies
------------------------------------------------------------------------------------------

                 Key: HHH-4760
                 URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-4760
             Project: Hibernate Core
          Issue Type: Bug
          Components: envers
    Affects Versions: 3.5.0-Beta-2
            Reporter: Erik-Berndt Scheper


NotAuditedException occurs when auditReader.getRevisions() is called for javassist proxies

In my code I see the following stacktrace if I try to retrieve the revision of a javassist proxy: 

org.hibernate.envers.exception.NotAuditedException: nl.ibgroep.bap.model.domain.persoon.Ouder_$$_javassist_1 is not versioned!
	at org.hibernate.envers.reader.AuditReaderImpl.getRevisions(AuditReaderImpl.java:126)
	at nl.ibgroep.bap.dao.impl.AuditRevisionJpaDaoImpl.getRevisionsFor(AuditRevisionJpaDaoImpl.java:58)


Ouder_$$_javassist_1.class is a Hibernate generated javassist proxy for Ouder.class, which is versioned. 

Code:
		AuditReader vr = AuditReaderFactory.get(this.entityManager);
		Class clazz = persistentObject.getClass();
		List<Number> revisionNumbers = vr.getRevisions(clazz, persistentObject.getId());
		

I am able to work around this issue with the following code:
		AuditReader vr = AuditReaderFactory.get(this.entityManager);
		Class clazz = persistentObject.getClass();
		if (persistentObject instanceof javassist.util.proxy.ProxyObject) {
			if (LOGGER.isDebugEnabled()) {
				StringBuilder output = new StringBuilder("Found javassist ProxyObject for revision: class= ");
				output.append(clazz.getSimpleName());
				output.append("; superclass= ").append(clazz.getSuperclass().getSimpleName());
				output.append("; interfaces= ").append(Arrays.asList(clazz.getInterfaces()).toString());
				LOGGER.debug(output.toString());
			} 
			clazz = clazz.getSuperclass();
		}
		List<Number> revisionNumbers = vr.getRevisions(clazz, persistentObject.getId());


However, a fix in envers would be greatly appreciated.
