Error description
Under the mixed environment such as WebSphere Application Server V7.0.0.0 and V7.0.0.1 or higher, and seting IBM_CS_WIRE_FORMAT_VERSION to 6.1.0 in the custom property of CoreGroup, the JVM encountered a panic situation and is unable to startup.
Local fix
Using IBM_CS_WIRE_FORMAT_VERSION as 6.0.2.9 (not using 6.1)

The null attribute that triggered the exception is the ham protocol version.
Problem conclusion
This issue was resolved by adding code to initialize the null attribute (ham protocol version) that was attempting to be streamed. The fix for this APAR is currently targeted for inclusion in fix packs 6.1.0.31 and 7.0.0.9.
