Error description

  • If portlet fragment caching is enabled, the portlet container
    may throw a NullPointerException when rewriting a portlet URL.
    If a portlet supports two phase rendering and portlet fragment
    caching is enabled, the portlet container may commit the
    response too early in the render headers phase.

    If portlet fragment caching is enabled, the portlet container
    may throw a NullPointerException when rewriting a portlet URL.
    If a portlet supports two phase rendering and portlet fragment
    caching is enabled, the portlet container may commit the
    response too early in the render headers phase.
    

Problem conclusion

  • The portlet container code is changed to correctly handle URL
    parameters and to commit the response only if required when
    rewriting cached markup.
    
    The fix for this APAR is currently targeted for inclusion in
    fix packs 8.0.0.10 and 8.5.5.4.  Please refer to the
