    ****************************************************************
    When com.ibm.websphere.monitor.*=all tracing is enabled, the
    ConnectionPoolStats MBean is not available and trace.log shows
    the following exception:
    
    <Exception java.lang.NullPointerException caught while calling
    toString() on object
    com.ibm.websphere.monitor.meters.Counter@69746bdc>
    

Problem conclusion

  • This problem only happens if the feature monitor-1.0 is enabled
    and com.ibm.websphere.monitor.*=all is also enabled. The code
    has been corrected.
    
    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:
    http://www.ibm.com/support/docview.wss?rs=180&uid=swg27004980
    

Temporary fix

  • The workaround is to use the following trace spec:
    com.ibm.websphere.monitor.jmx.*=all:\
    com.ibm.websphere.monitor.meters.Meter*=all:\
    com.ibm.websphere.monitor.meters.Counter*=all:\
    com.ibm.websphere.monitor.meters.Gauge*=all:\
    com.ibm.websphere.monitor.meters.StatisticsMeter=all:\
    com.ibm.websphere.monitor.meters.StatisticsReading=all
