> 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.
