JDK-8238358 - Implementation of JEP 371: Hidden Classes
Description
JDK-8238358 introduced hidden classes with internal names like com/example/Foo.1234 that get changed to com.example.Foo/1234 by Class.getName() which are not properly handled by MetaUtil's toInternalName and internalNameToJava

This used to work on the assumption that the internal class names didn't contain the . character and that java class names didn't contain the / character except for lambdas (which are now treated as hidden classes as well), an assumption that no longer holds.
