    ****************************************************************
    IBM WebSphere Application Server delivers the national language
    support resources in separate jars called fragments.  When
    uninstalling a liberty feature from the running server instance
    the national language support fragments are also uninstalled
    dynamically.  There is a issue in the code that handles when the
    fragments are uninstalled.  That code is trying to access
    resources out of the uninstalled fragments which leads to the
    FFDC reported.  The code reports the FFDC and correctly
    continues without any detrimental effect on the functionality of
    the server.
    

Problem conclusion

  • The scenario when fragments are uninstalled is correctly handled
    but the FFDC with the  java.lang.IllegalStateException is
    incorrectly reported.  The fix is to avoid reporting the FFDC
    when there is no detrimental effect on the functionality of the
    server.
    
    The fix for this APAR is currently targeted for inclusion in fix
    pack 17.0.0.4.  Please refer to the Recommended Updates page for
    delivery information:

Temporary fix

  • Ignore the FFDC when it is reporting the exception:
    java.lang.IllegalStateException: Module has been uninstalled.
