When a .NET application attempts to read or write via the extend connector, the following warning message appears:

2009-04-06 14:44:21.996/248754.321 Oracle Coherence EE 3.4.2/411p1 <Warning>
(thread=Proxy:ExtendTcpProxyService:TcpAcceptorWorker:95, member=6): The serializer used by cache
"CarrierCache" (com.tangosol.io.DefaultSerializer@a6e0a9) is incompatible with the serializer configured for service "Proxy:ExtendTcpProxyService:TcpAcceptor"
(com.tangosol.io.pof.ConfigurablePofContext@1e779a1); therefore, cached keys and values will be converted via serialization. This will result in increased CPU and memory utilization. If possible, consider reconfiguring either serializer.
