      The Java VM spec chapter 5.4.3a Class and Interface Resolution reads:
      ...
      7.Finally, access permissions to C are checked:
               If D does not have permission to access C, class or interface resolution throws an
               IllegalAccessError.

      But the attached test shows that interface case don't throw an IllegalAccessError
      when a superinterfaces is not accessible.

      --------------------------------- AlienInterface.jasm

      package res;

      interface AlienInterface
      {
      } // end Class AlienInterface

      --------------------------------- TestClass.jasm

      class TestClass implements res/AlienInterface {}

      --------------------------------- resolveClass00704.java

      import java.io.PrintStream;

      public class resolveClass00704 {

        public static int run(String argv[], PrintStream out) {

      try{
      Class.forName("TestClass");
      out.println("No exception");
      return 2;
      } catch (IllegalAccessError e) {
      return 0;
      } catch (Throwable e) {
      out.println("Unexpected exception " + e);
      return 2;
      }
        }

        public static void main(String argv[]) {
      System.exit(run(argv, System.out) + 95/*STATUS_TEMP*/);
        }
      }
