class IsInstanceTest extends Thread implements Cloneable
{
  static void main(String args[])

      else
	fail("IsInstanceTest is not instance of java.lang.Object");

      if (test instanceof java.lang.Cloneable)
	pass("IsInstanceTest is instance of java.lang.Cloneable");
      else
	fail("IsInstanceTest is not instance of java.lang.Cloneable");

      if (test instanceof java.lang.Runnable)
	pass("IsInstanceTest is instance of java.lang.Runnable");
      else
