Normally casting works fine for me but I just ran into a problem where if I invoke Session.get(Image.class.getName(), someID) then try to cast the returned object to CachedImage this exception is thrown:
java.lang.ClassCastException: com.be.desktopbeautifier.database.Image$$EnhancerByCGLIB$$eb0e25cb
If I use Session.get(CachedImage.class.getName(), someID) I get this warning message instead:
Narrowing proxy to interface com.be.desktopbeautifier.database.CachedImage - this operation breaks ==
I know for a fact that someID refers to a CachedImage so a ClassCastException should not be occuring here. Is there something wrong with my mapping file or is this a bug in Hibernate's proxy handling of interfaces?
