Closed as program error.
Error description
There is a deserialization issue after WAS failover. Consider a serialized attribute set on the SIP session, when the attribute contains a member with a reference to its parent (the attribute). Upon failover, the attribute is deserialized and its member contains a reference to a new instance of its parent.

Problem summary
**************************************************************** * USERS AFFECTED: IBM Websphere Application Server V7.0 * * Feature Pack for Communications Enabled * * Applications (CEA) Session Initiation * * Protocol (SIP) users * **************************************************************** * PROBLEM DESCRIPTION: Upon failover, there is a * * deserialization issue with attributes * * on the SIP session that holds cyclic * * references. * **************************************************************** * RECOMMENDATION: * **************************************************************** When serializing or deserializing an attribute in ReplicationOutputStream and ReplicationInputStream we used ObjectOutputStream.writeUnshared() and ObjectInputStream.readUnshared() accordingly.
Problem conclusion
Added a custom property: replicate.sip.object.attribute. When this is set to true, ReplicationOutputStream and ReplicationInputStream will use ObjectOutputStream.writeObject() and ObjectInputStream.readObject() accordingly. The fix for this APAR is currently targeted for inclusion in fix pack 1.0.0.11.
