Problem summary
**************************************************************** USERS AFFECTED: This issue affects users of the IBM MQ classes for Java Message Service (JMS) Administration tool called JMSAdmin who display an MQQueue object stored in Java Naming and Directory Interface (JNDI) repository. Platforms affected: AIX, HP-UX Itanium, HP-UX PA-RISC, HP-UX OpenVMS, IBM iSeries, Linux on Power, Linux on S390, Linux on x86, Linux on x86-64, Linux on zSeries, Solaris SPARC, Solaris x86-64, Windows **************************************************************** PROBLEM DESCRIPTION: IBM MQ classes for Java Message Service (JMS) Administration tool JMSAdmin is used to create Java Naming and Directory Interface (JNDI) administered objects, such as ConnectionFactories, Queues and Topics. If the JMSAdmin tool was used to display an MQQueue object that was stored in the JNDI repository, then a java.lang.ClassCastException was thrown while parsing the value of the UNMAPPABLEREPLACEMENT property. --------------- InitCtx> DIS Q(Q2) CCSID(1208) DESCRIPTION(Queue created from Queue 'Q2' on Queue Manager 'QM1' at '26-August-2015 10:35:18') ENCODING(NATIVE) EXPIRY(APP) FAILIFQUIESCE(YES) MDMSGCTX(DEFAULT) MDREAD(NO) MDWRITE(NO) MSGBODY(UNSPECIFIED) PERSISTENCE(APP) PRIORITY(APP) PUTASYNCALLOWED(AS_DEST) QMANAGER(QM1) QUEUE(TESTQUEUE) READAHEADALLOWED(AS_DEST) READAHEADCLOSEPOLICY(DELIVER_ALL) RECEIVECCSID(1208) RECEIVECONVERSION(CLIENT_MSG) REPLYTOSTYLE(DEFAULT) TARGCLIENT(JMS) UNMAPPABLEACTION(REPORT) Exception in thread "main" java.lang.ClassCastException: java.lang.Byte incompatible with java.lang.String at com.ibm.mq.jms.admin.JMSAdmin.doDisplay(JMSAdmin.java:1412) at com.ibm.mq.jms.admin.JMSAdmin.execCommand(JMSAdmin.java:451) at com.ibm.mq.jms.admin.JMSAdmin.commandLoop(JMSAdmin.java:335) at com.ibm.mq.jms.admin.JMSAdmin.(JMSAdmin.java:247) at com.ibm.mq.jms.admin.JMSAdmin.main(JMSAdmin.java:1863) --------------- This was caused by incorrectly attempting to cast a java.lang.Byte value to a java.lang.String to display to the user.
Problem conclusion
The IBM MQ classes for JMS Administration tool JMSAdmin, has been updated to remove the casting of property values to java.lang.String objects. The property values for displayed Administered objects stored in the Java Naming and Directory Interface (JNDI) repository are converted to java.lang.String objects without casting, thus, preventing a java.lang.ClassCastException from being thrown. --------------------------------------------------------------- The fix is targeted for delivery in the following PTFs: Version Maintenance Level v8.0 8.0.0.3 The latest available maintenance can be obtained from 'WebSphere MQ Recommended Fixes' http://www-1.ibm.com/support/docview.wss?rs=171&uid=swg27006037 If the maintenance level is not yet available information on its planned availability can be found in 'WebSphere MQ Planned Maintenance Release Dates' http://www-1.ibm.com/support/docview.wss?rs=171&uid=swg27006309 ---------------------------------------------------------------
