Proxy.getProxyClass is proposed to be deprecated in Java SE 9 - you'll 
see the changes in the jake forest, they just haven't got to JDK 9 main 
line yet. There is also a very clear list of restrictions in the updated 
javadoc. Since you are going into jdk9/client then maybe the simplest is 
to just reference the restrictions in the Proxy class.
