Error description
A NullPointerException is thrown when an a WebSphere MQ V7 classes for Java application has set the format of an com.ibm.mq.MQMessage to NULL before attempting a PUT to a queue, for example using the following code snippet: MQQueueManager qm = new MQQueueManager("sampleQM"); MQQueue q = qm.accessQueue("Q1", MQC.MQOO_OUTPUT); MQMessage m = new MQMessage(); m.format = null; q.put(m, new MQPutMessageOptions());
Local fix
LOCAL FIX: Initialize the message descriptor format to something other than NULL
Problem summary
**************************************************************** USERS AFFECTED: This issue affects a user of the WebSphere MQ classes for Java version 7.0 and 7.1, who have applications which set the format of an WebSphere MQ Message to NULL before putting the message to a queue. Platforms affected: All Distributed (iSeries, all Unix and Windows) +Java **************************************************************** PROBLEM SUMMARY: A NullPointerException was thrown when an application set the format of an com.ibm.mq.MQMessage to NULL before attempting a PUT to a queue. This worked successfully when using the WebSphere MQ V6 classes for Java.
Problem conclusion
The code was modified such that when the application sets the format of an com.ibm.mq.MQMessage to NULL, and then attempts to put the message to a queue, the format is updated to its default value of 8 space characters, " ". This replicates the behavior of the WebSphere MQ V6 classes for Java, and prevents the NullPointerException from being thrown. --------------------------------------------------------------- The fix is targeted for delivery in the following PTFs: v7.0 Platform Fix Pack 7.0.1.9 -------- -------------------- Windows U200337 AIX U849391 HP-UX (PA-RISC) U849723 HP-UX (Itanium) U849728 Solaris (SPARC) U849724 Solaris (x86-64) U849730 iSeries 7.0.1.9 Linux (x86) U849725 Linux (x86-64) U849729 Linux (zSeries) U849726 Linux (Power) U849727 v7.1 Platform Fix Pack 7.1.0.2 -------- -------------------- Windows 7.1.0.2 AIX 7.1.0.2 HP-UX (Itanium) 7.1.0.2 Solaris (SPARC) 7.1.0.2 Solaris (x86-64) 7.1.0.2 iSeries 7.1.0.2 Linux (x86) 7.1.0.2 Linux (x86-64) 7.1.0.2 Linux (zSeries) 7.1.0.2 Linux (Power) 7.1.0.2 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 ---------------------------------------------------------------
