      The original fix of 8087223 caused test failures, led two bugs filed: 8143317 and 8143320. The test failures will be addressed in the two bugs. The fix itself has no problem but the test cases failed on it should be changed so the fix should be integrated again.

      The following invoke instructions are successfully executed:
         invokestatic #3; //InterfaceMethod C.foo:()V
         invokestatic #3; //Method I.foo:()V

      where
        class C {...}
        interface I {...}

      JVMS-5.4.3.3 Method Resolution:
       " If C is an interface, method resolution throws an IncompatibleClassChangeError."
      JVMS-5.4.3.4 Interface Method Resolution:
       "If C is not an interface, interface method resolution throws an IncompatibleClassChangeError"

      Test case attached(IntfMethod.java):
      $ java -Xverify:all IntfMethod
