Troubleshooting
Problem
Upgrading IBM Sterling B2B Integrator (SBI) to version 5.2.5 requires a JDK upgrade to IBM Java 7 SR 7 FP1 or higher. Once SBI was successfully upgraded to 525 and JDK 7 SR7 FP1 JGoups UDP multicasting (cluster communications) stopped working, and errors are thrown in the noapp and jetty log(s)
Symptom
JGroups UDP multicasting (used in cluster communications for load distribution) stops working, and the following errors are thrown in the noapp and jetty log(s)
Noapp:

Cluster Test BPs fail, load distribution fails to occur.
Cause
It has been determined that the catalyst for this issue was disabling" IPv6 on the Windows Network Configuration by unchecking Internet Protocol Version 6 (TCP/IPv6) under Local Area Connection. This was an intended action as the intent was to disable IPv6.
This has been diagnosed as a JDK bug.
Environment
Microsoft Windows Server
JDK version less than Java 7 Release 0 SR 9
Diagnosing The Problem
Cluster Test BP fails
http://www-01.ibm.com/support/knowledgecenter/SS3JSW_5.2.0/com.ibm.help.sys_maint_cklist.doc/SI_SampleClusterTestBP.html?lang=en
The noted errors above are found in the noapp and jetty logs
Resolving The Problem
The JDK issue is resolved in Java 7 SR 9 (and higher). The JDK may be obtained on Fix Central
Other workarounds include, "enabling" IPv6 on the Network Configuration as well as switching to TCP for the JGroups Property String found in jgroups_cluster.properties
