    ****************************************************************
    Websphere packages a version of SLF4J for use by weld,
    but this instance of SLF4J was not isolated to Websphere's
    internal classes and could cause problems if it was picked up
    by a customer's application.
    

Problem conclusion

  • The instance of SLF4J packaged with websphere is now
    correctly isolated to websphere's internal classes.
    
    The fix for this APAR is currently targeted for inclusion in
    fix pack 9.0.0.5 and liberty 17.0.0.3.  Please refer to the
