      Description



      Name: dmR10075 Date: 08/27/2003


      Download and install j2ee 1.3.1 with tutorial, start Tutorial, after
      creation of first Bean you will get the following deadlock. Reproduced
      using 1.5.0b16, on Linux/XAWT. This seems to be a generic problem - the
      code which causes a deadlock can as well deadlock with any other
      toolkit.
