Sun GlassFish Communications Server 1.5 Release Notes

Mismatch of old and new classes is created when imqjmsra.jar is loaded before upgrade (6740794)


During Application Server startup, the server checks the Message Queue version. If the Message Queue version is incorrect, then the server upgrades using the imqjmsra.jar. This upgrade JAR and its classes will not be available to the server until the next restart of Application Server. This situation only occurs if Message Queue is upgraded alone, or if Application Server is patched alone. A side effect of this situation is that sometimes Application Server does not start.


Both Message Queue and Application Server need to be maintained at the same patch level, or restart the Application Server.
