I get a NullPointerEx from PIORB with the following stack trace:

Exception occurred: java.lang.NullPointerException (to be caught at:
com.sun.corba.ee.internal.CosNaming.BootstrapRequestHandler.dispatch(),
line=405, bci=199) thread="RequestProcessor",
com.sun.corba.ee.internal.Interceptors.PIORB.invokeServerPIEndingPoint(),
line=705, bci=6

RequestProcessor[1] where
  [1] com.sun.corba.ee.internal.Interceptors.PIORB.invokeServerPIEndingPoint
(PIORB.java:705)
  [2] com.sun.corba.ee.internal.iiop.ServerResponseImpl.<init>
(ServerResponseImpl.java:68)
  [3] com.sun.corba.ee.internal.iiop.ServerResponseImpl.<init>
(ServerResponseImpl.java:32)
  [4] com.sun.corba.ee.internal.iiop.ServerRequestImpl.createResponse

  [5] com.sun.corba.ee.internal.CosNaming.BootstrapRequestHandler.dispatch
(BootstrapServer.java:348)
  [6] com.sun.corba.ee.internal.iiop.ORB.process (ORB.java:264)
  [7] com.sun.corba.ee.internal.iiop.RequestProcessor.process
(RequestProcessor.java:89)
  [8] com.sun.corba.ee.internal.orbutil.ThreadPool$PooledThread.run
(ThreadPool.java:91)


After this the RequestProcessor returns without replying
to the client, because ServerRequestImpl.createSystemExceptionResponse
calls PIORB.setServerPIInfo which again throws NullPointerEx.
So the client hangs.
