interfaces for Proxies are not regonized as interfaces ------------------------------------------------------ Key: HHH-1189 URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-1189 Project: Hibernate Core Issue Type: Bug Components: core Affects Versions: 3.1 rc3 Environment: Discovered on Hibernate 3.0, still present in 3.1rc3 Reporter: Tobias Assignee: Steve Ebersole Fix For: 3.6.0.Beta4 Attachments: eg.zip Original Estimate: 1h Time Spent: 43m Remaining Estimate: 17m In org.hibernate.tuple.PojoEntityTuplizer line 119 reads: if ( !proxyInterface.isInterface() ) { and should be if ( !subclassClass.isInterface() ) { So the code then would look like this: Subclass subclass = ( Subclass ) iter.next(); Class subclassProxy = subclass.getProxyInterface(); Class subclassClass = subclass.getMappedClass(); if ( subclassProxy!=null && !subclassClass.equals( subclassProxy ) ) { if ( !subclassProxy.isInterface() ) { // HERE! throw new MappingException( "proxy must be either an interface, or the class itself: " + subclass.getEntityName() ); } proxyInterfaces.add( subclassProxy ); } After that change the specified interfaces for subclass proxies are regonized as such. Without this patch the superclass is checked, which may not have/be an interface as proxy class.
