      The more-specific method analysis fails to acknowledge that the function types of two functional interface types being compared may be generic.

      Example:
      interface Foo {
        <T> ArrayList<T> m();
      }
      interface Bar {
        <E> List<E> m();
      }

      Presumably all checks comparing the two function types should be subject to alpha-renaming (8.4.4); and an additional check should ensure that the type parameters are equivalent.

      Similar changes are necessary in 18.5.4.
