Error description

  • Product Release and Version Information: WebSphere Application
    Server Base Version 7.0 with Feature Pack for Service Component
    Architecture (SCA) V1.0.1.
    
    Problem Description:
    
    The reference to ConfigurationContext in the ListenerMananger
    being set in the WASAxis2Servlet.java is leading to
    SCAClassLoaders being retained in memory.

Problem summary

    ****************************************************************
    * RECOMMENDATION:  Install a fix pack containing this APAR.    *
    ****************************************************************
    WASAxis2Servlet initializes a ListenerManager with references
    to a defaultConfigurationContext.  For applications which
    contain servlets, this causes a memory leak in the WebSphere
    Application Server.
    

Problem conclusion

  • The defaultConfigurationContext was not being
    used by the ListenerManger, so the jax-ws runtime has been
    modified such that the defaultConfigurationContext is no
    longer set.
    
    The fix for this APAR is currently targeted for inclusion in fix
    pack 7.0.0.19. Please refer to the Recommended Updates page for
    delivery information:
