Simon Laws commented on TUSCANY-3312:
-------------------------------------

The same sort of pattern occurs in 

  JavaElementImpl
  DataTypeImpl
  SCAProxy

So am about to check in fixes for those also

> In JavaInterfaceFactoryImpl there's a cache....
> private Map<Class<?>, JavaInterface> cache  = Collections.synchronizedMap(new WeakHashMap<Class<?>, JavaInterface>());
> But 
> public class JavaInterfaceImpl extends InterfaceImpl implements JavaInterface {
>     private String className;
>     private Class<?> javaClass;
> So it seems that Class<?> javaClass; should really be a weak reference
