[jboss-jira] [JBoss JIRA] Closed: (JASSIST-85) IllegalAccessError when trying to call clone() on a class generated by ProxyFactory

IllegalAccessError when trying to call clone() on a class generated by ProxyFactory ----------------------------------------------------------------------------------- Key: JASSIST-85 URL: https://jira.jboss.org/jira/browse/JASSIST-85 Project: Javassist Issue Type: Bug Affects Versions: 3.10.0.GA Reporter: Tobias Meyer Assignee: Shigeru Chiba Fix For: 3.12.0.GA Hibernate 3.3 uses javassist (by default) to generate LazyInitializer Objects. If a lazily loaded object implements the clone() method, and makes it public, there will be a runtime IllegalAccessError because the javassist proxy object exports the protected definition of Object.clone() instead of the definition in the MethodHandler's Interface. The supplied patch makes the ProxyFactory to never reduce the visibility of a public method, even if implemented in a higher interface or the superclass. Normally the java compiler would catch such an error, so this is assumed to be save. Side effect is of course that a superclass method given to ProxyFactory might not be called as before because a public definition of the MethodHandler (Interface) overloads it.
