      POA.destroy(false, true) method throws unexpected ConcurrentModificationException

      See example:
      ------------- ORBTest.java ---------------------
      import org.omg.CORBA.*;
      import org.omg.PortableServer.*;


      public class ORBTest {
                                                                     
          public static void main(String argv[]) {
      try {
      ORB orb = ORB.init(argv, null);

      POA rootPOA = POAHelper.narrow(orb.resolve_initial_references("RootPOA"));

      String names [] = {"Test", "Test1", "Test2",
      "Test with whitespaces"
      };

      POA testPOA = rootPOA.create_POA(names [0], null, new Policy[0]);
      POA children[] = {
      testPOA.create_POA(names [0], null, new Policy[0]),
      testPOA.create_POA(names [1], null, new Policy[0]),
      testPOA.create_POA(names [2], null, new Policy[0]),
      testPOA.create_POA(names [3], null, new Policy[0])};

      POA testPOA2 = children[1].create_POA("child of child", null, new Policy[0]);
       
      testPOA.destroy (false, true);
      System.out.println("Okay");

      } catch(Exception e) {
      System.out.println("ERROR : " + e);
      e.printStackTrace(System.out);
      }
          }

      }
