    Description

      The current implementation of LambdaMetaFactory creates VM-anonymous class which does not conform to the standard access control rules.

      This issue tracks the conversion of LambdaMetaFactory from using VM-anonymous class to hidden class.

      A hidden class is subject to standard access control rules.

      One non-standard access that VM-anonymous class has is that
      a VM-anonymous class can always access protected members of a superclass in a different package, which is not allowed by the rules of JVMS 5.4.4.
