Error description
When an application using the WebSphere MQ V7 classes for Java Message Service (JMS) receives an ObjectMessage that was sent by an application using the WebSphere MQ V6 classes for JMS, a StreamCorruptedException occurs. The stack trace associated with the exception is shown below: IO Exceptionjava.io.StreamCorruptedException: invalid stream header:7372002B at java.io.ObjectInputStream.readStreamHeader (ObjectInputStream.java:794) at java.io.ObjectInputStream.<init>(ObjectInputStream.java:291) at com.ibm.mq.MQObjectInputStream.<init> (MQObjectInputStream.java:98) at com.ibm.mq.MQMessage.readObject(MQMessage.java:1536) ...
Local fix
Problem summary
**************************************************************** USERS AFFECTED: This issue affects users of WebSphere MQ V7 classes for Java Message Service (JMS) applications that receive ObjectMessages. Platforms affected: All Distributed (iSeries, all Unix and Windows) +Java **************************************************************** PROBLEM SUMMARY: ObjectOutputStream and ObjectInputStream objects in the WebSphere MQ V7 classes for JMS were being cached over multiple readObject() and writeObject() calls. As the stream header information for messages sent by applications using the V6 classes for JMS was different to the header information used by the V7 classes for JMS, once the V7 classes for JMS had received a message sent by a V7 application, they could not process any ObjectMessages sent by a V6 application.
Problem conclusion
The WebSphere MQ V7 classes for JMS have been updated to create a new ObjectOutputStream and ObjectInputStream every time the readObject() or writeObject() methods are called. --------------------------------------------------------------- The fix is targeted for delivery in the following PTFs: v7.0 Platform Fix Pack 7.0.1.5 -------- -------------------- Windows U200324 AIX U839183 HP-UX (PA-RISC) U839621 HP-UX (Itanium) U839626 Solaris (SPARC) U839622 Solaris (x86-64) U839628 iSeries tbc_p700_0_1_5 Linux (x86) U839623 Linux (x86-64) U839627 Linux (zSeries) U839624 Linux (Power) U839625 v7.0 Currently any fixes planned for v7.0 will be fixed in 7.0.1.* and not in 7.0.0.* 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 ---------------------------------------------------------------
