Hi Pete, I've found a consistency issue in the global configuration: TransportConfiguration has a reference to Transport coming from transportClass attribute resolution. However, when you go to SerializationConfiguration, you see Class<? extends Marshaller> rather than Marshaller as resolved from marshallerClass. I think this should Marshaller as opposed to Class<? extends Marshaller>. WDYT? Cheers, -- Galder Zamarreño Sr. Software Engineer Infinispan, JBoss Cache
