    ****************************************************************
    The application server sets an unexpected parent reference
    on a library classloader that supports a shared library that
    is configured as both isolated and associated to the server
    as described in the following Knowledge Center topic.
    https://www.ibm.com/support/knowledgecenter/en/SSAW57_9.0.0/com.
    ibm.websphere.nd.multiplatform.doc/ae/tcws_sharedlib_server.html
    Classloading errors will occur whenever the library
    classloader attempts to load classes made visible by
    the WebSphere OSGi classloader network and the WebSphere
    extensions clasloader.
    

Problem conclusion

  • Apply APAR PI91331 to ensure the application server sets the
    expected parent reference on any library classloader that
    supports a shared library configured as isolated and is also
    associated to the server.
    
    The fix for this APAR is currently targeted for inclusion in
    fix packs 9.0.0.11 and 8.5.5.15.  Please refer to the
