  * the class MemberNameTable without a crash in the VM fastdebug mode.
  * The original issue was that the InstanceKlass _initial_method_idnum was

  * The expected/correct behavior: The test does not crash nor throw any exceptions.
  * All the invocations of the defaultMethod() must be completed successfully.
