    logstashCollector-1.0 with garbage collection events enabled on
    IBM Java 8 SR 5 FP 6 or later may not capture garbage collection
    events correctly.
    This may result in the following error in the FFDC logs
    directory:

Problem conclusion

  • Code was added to use the monitoring-api.jar found in the Java
    directory to interface with IBM Health Center before defaulting
    to an embedded monitoring-api.jar found in Liberty.
    
    The fix for this APAR is currently targeted for inclusion in fix
    pack 18.0.0.2.  Please refer to the Recommended Updates page for
