Well, there is already one example of an agent that manages access to 
module private code which is widely in use by the community. On JDK9+ 
Byteman allows injected code to access methods that are not exported by 
modules, using the module open APIs provided to class Instrumentation. 
It does so using its own module layer and associated controller. It is 
also implemented to behave compatibly on JDK8 where it achieves the same 
outcome using reflection. Most notably, on JDK9+ Byteman avoids exposing 
those unexported methods to anything other than the injected code.
