That's in place.

Vote to reopen this as the constructor for the AnnotationRevisionMetadata object in the EnversRevisionRepositoryImpl hard codes the UNKNOWN type for the revision.

Code in EnversRevisionRepositoryImpl:

private RevisionMetadata<?> getRevisionMetadata(Object object) {
    return (RevisionMetadata)(object instanceof DefaultRevisionEntity 
        ? new DefaultRevisionMetadata((DefaultRevisionEntity)object) 
        : new AnnotationRevisionMetadata(object, RevisionNumber.class, RevisionTimestamp.class));
  }

This should become:

private RevisionMetadata<?> getRevisionMetadata(Object object) {
    return (RevisionMetadata)(object instanceof DefaultRevisionEntity 
    ? new DefaultRevisionMetadata((DefaultRevisionEntity)object) 
    : new AnnotationRevisionMetadata(object, RevisionNumber.class, RevisionTimestamp.class, object.getType()));
  }

NOTE the change is giving the type into the constructor.

I don't know whether it's possible to retrieve the type from the object, or from somewhere else....
