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

Richard Reynolds commented on JASSIST-85:
-----------------------------------------

I believe when you applied the patch you missed a step.  

Check your 3.11.0.GA sources and you will see that you missed removing this line. 

- hash.put(key, methods[i]); 

So the IllegalAccessError still exists in the new jar.

> 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.
