Is there really a jdk.proxy1 module?

[David M. Lloyd]

Or better yet, to the module defining the proxy interface(s)... of 
course, then you must ensure that they all are from the same module.

This is another area where having per-module class loaders is superior: 
the getProxyClass()/newProxyInstance() methods already expect a class 
loader for the first argument, so you can select a module which has 
visibility to all the interfaces if so desired.
