APAR status

Closed as program error.

Error description

WebServices Atomic Transactions (WS-AT) between v7 and v6.1
failed when a WS-AT paticipant cluster does Peer Recovery
during a WS-AT operation.

In such case, the WS-AT Initiator keeps sending WS-AT messages
to the dede JVM even though the Peer server has already taken
recovery the transacion.

This is caused by a serilization problem in Core Gourp Bridge
between v7 and v6.1.

****************************************************************
When version 6.0.2 or 6.1 core group bridges communicate with
7.0 bridges using the "IBM_CS_HAM_PROTOCOL_VERSION=6.0.2.31"
core group protocol, there is an incompatibility in one of the
base messages that leads to the following exception:

java.io.InvalidClassException
com.ibm.ws.cgbridge.core.impl.InterCGBridgePMGEvents.onMessage 1
Exception = java.io.InvalidClassException

Problem conclusion

Serialized data was changed in the 7.0 version of the core
group bridge to enable communication with version 6.0.2 and 6.1.
