Problem conclusion

  • Modified the code to get the poolmanager from
    ConnectionFactoryDetails before using the poolmanager object
    and also to check if poolmanager object is null to avoid
    NullPointerException.
    
    APAR PM35291 is currently targeted for inclusion in Service
    Level (Fix Pack) 7.0.0.19 of WebSphere Application Server V7.0.
