Core reflection doesn't actually add read edges of course, it instead 
just assumes readability. This avoids needing to change code using core 
reflection when migrating that code to explicit modules.

The reason that java.lang.invoke checks readability is because it's 
aligned with bytecode. It would be a significant change if the access 
checks in java.lang.invoke differed to bytecode.
