      Description



      Name: aaR10142 Date: 07/11/2001



      CORBA method invocations work unstable.
      See an example.
      It creates corba object and calls its method 100 times.
      Sometimes org.omg.CORBA.OBJECT_NOT_EXIST exception is thrown by the method.

      --------------- Test.idl -------------------
      module TestApp {
          interface Test {
              string changeString();
          };
      };
      ------------- ORBTest.java ---------------------
