Error description
When using the WebSphere MQ V7 Classes for Java, and trying to add a new RFH2 header to an MQMessage, the call to the method MQHeaderList.write produces the following exception: . java.lang.ArithmeticException: / by zero at com.ibm.mq.headers.internal.MQMessageWrapper.shuffle (MQMessageWrapper.java:144) at com.ibm.mq.headers.MQHeaderList.write(MQHeaderList.java:407) at com.ibm.mq.headers.MQHeaderList.write(MQHeaderList.java:360)
Local fix
Create a new MQMessage, copy all the MQMD attributes and rewrite the body just to add headers.
Problem summary
**************************************************************** USERS AFFECTED: This issue affects users of: - The WebSphere MQ V7 classes for Java. - The WebSphere MQ V7 classes for JMS. - The WebSphere MQ V7 Resource Adapter. - The WebSphere MQ V7 OSGi bundles. - The WebSphere Application Server V7 WebSphere MQ messaging provider. - The WebSphere Application Server V8 WebSphere MQ messaging provider. - The WebSphere Application Server V8.5 WebSphere MQ messaging provider. - The WebSphere Application Server V6.1 WebSphere MQ messaging provider who have configured the WebSphere variable MQ_INSTALL_ROOT to point to a WebSphere MQ V7 installation. who add a new RFH2 header to an MQMessage which has no existing RHF2 headers. Platforms affected: All Distributed (iSeries, all Unix and Windows) +Java +Java zOS **************************************************************** PROBLEM SUMMARY: The WebSphere MQ classes for JMS/Java expected every MQMessage to have at least one pre-existing header when adding a new RFH2 header. In the situation where the MQMessage had no pre-existing headers, the code would throw the described ArithmeticException.
Problem conclusion
The code has been altered to ensure that a new RFH2 header can be added to an MQMessage which has no existing headers. --------------------------------------------------------------- The fix is targeted for delivery in the following PTFs: v7.0 Platform Fix Pack 7.0.1.10 -------- -------------------- Windows U200352 AIX U853055 HP-UX (PA-RISC) U853082 HP-UX (Itanium) U853087 Solaris (SPARC) U853083 Solaris (x86-64) U853089 iSeries 7.0.1.10 Linux (x86) U853084 Linux (x86-64) U853088 Linux (zSeries) U853085 Linux (Power) U853086 zOS 7.0.1.10 v7.1 Platform Fix Pack 7.1.0.3 -------- -------------------- Windows 7.1.0.3 AIX 7.1.0.3 HP-UX (Itanium) 7.1.0.3 Solaris (SPARC) 7.1.0.3 Solaris (x86-64) 7.1.0.3 iSeries 7.1.0.3 Linux (x86) 7.1.0.3 Linux (x86-64) 7.1.0.3 Linux (zSeries) 7.1.0.3 Linux (Power) 7.1.0.3 zOS 7.1.0.3 Platform v7.5 -------- -------------------- Multiplatforms 7.5.0.1 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 ---------------------------------------------------------------
