    When running an Aries application, a null pointer exception
    (NullPointerException) can occur while attempting to retrieve a
    system property while handling a request to a servlet in the
    Aries application.
    
    The null pointer occurs because no code source attached to a
    protection domain which is used to obtain the system property.
     The system property is obtain during JNDI processing while
    handling a request to a servlet of the Aries application.
    
    The problem is a duplicate of the Eclipse bugzilla defect
    282704, which was fixed in Equinox version 3.5.1.  For
