Peter Levart catches a bug in dynamic proxy code that adds read edge to proxy interfaces and all their superinterfaces.

A proxy class only needs to access the proxy interfaces and the types referenced in the method signature of all methods.

777 // set up proxy class access to proxy interfaces and superinterfaces
778 Deque<Class<?>> deque = new LinkedList<>(interfaces);
779 Set<Class<?>> visited = new HashSet<>();
780 while (!deque.isEmpty()) {
781 Class<?> c = deque.poll();
782 if (!visited.add(c)) {
783 continue;
784 }
785 ensureAccess(target, c);
786
787 // add all superinterfaces
788 for (Class<?> intf : c.getInterfaces()) {
789 deque.add(intf);
790 }
791 }

The above loop adding all superinterfaces can be removed.
