Issue/Introduction

MQ Monitor agent monitoring IIB v9 (and IIB fieldpack monitoring IIB v10) both report an error message on shutdown

MQ Monitor agent: Exception in thread "Thread-9" java.lang.NoSuchMethodError: com/ibm/mq/jms/Cleanup.cleanup()V at com.wily.powerpack.websphereMQ.agent.MQMonitor.MBMonitor.MBStatisticsCleanup.cleanQueue(MBStatisticsCleanup.java:396) at com.wily.powerpack.websphereMQ.agent.MQMonitor.MBMonitor.MBStatisticsCleanup.doCleanup(MBStatisticsCleanup.java:362) at com.wily.powerpack.websphereMQ.agent.MQMonitor.MBMonitor.v7.MBTreeConfigMain.processCleaning(MBTreeConfigMain.java:639) at com.wily.powerpack.websphereMQ.agent.MQMonitor.MBMonitor.v7.MBTreeConfigMain.access$2(MBTreeConfigMain.java:606) at com.wily.powerpack.websphereMQ.agent.MQMonitor.MBMonitor.v7.MBTreeConfigMain$1.run(MBTreeConfigMain.java:224) IIB 10 field pack agent: Exception in thread "Thread-10" java.lang.NoSuchMethodError: com/ibm/mq/jms/Cleanup.cleanup()V (loaded from file:/opt/mqm/java/lib/com.ibm.mq.allclient.jar by [email protected]) called from class com.wily.powerpack.websphereMQ.agent.MQMonitor.MBMonitor.MBStatisticsCleanup (loaded from file:/opt/mqmmon/N1INWB01/iibagent/MQMonitor/MQMonitor.jar by [email protected]). at com.wily.powerpack.websphereMQ.agent.MQMonitor.MBMonitor.MBStatisticsCleanup.cleanQueue(MBStatisticsCleanup.java:396) at com.wily.powerpack.websphereMQ.agent.MQMonitor.MBMonitor.MBStatisticsCleanup.doCleanup(MBStatisticsCleanup.java:362) at com.wily.powerpack.websphereMQ.agent.MQMonitor.MBMonitor.v7.MBTreeConfigMain.processCleaning(MBTreeConfigMain.java:745) at com.wily.powerpack.websphereMQ.agent.MQMonitor.MBMonitor.v7.MBTreeConfigMain.access$2(MBTreeConfigMain.java:717) at com.wily.powerpack.websphereMQ.agent.MQMonitor.MBMonitor.v7.MBTreeConfigMain$1.run(MBTreeConfigMain.java:232)

There is no advserse impact of this message on functionality

Cause

The problem  relates to the MQ version in use the cleanup method has one variant in 8.0

void  cleanup(boolean runAtRegularIntervals)

https://www.ibm.com/support/knowledgecenter/en/SSFKSJ_8.0.0/com.ibm.mq.javadoc.doc/WMQJMSClasses/com/ibm/mq/jms/Cleanup.html

where as in 7.1 it has 2

void  cleanup()
void  cleanup(boolean runAtRegularIntervals)

The call made by the agent assumes the method wiith parameters is available

Environment

MQ monitor with MQ 7.5 or high and IIB / MB monitoring enabled - all agent versions up to 10.7 SP2

Resolution

A test fix has been verified for this and teh fix will be rolled into the next agent release
