Guys, If you create further implementations of BaseCacheStoreTest, could you make sure that the marshaller used is the one retrieved from getMarshaller() method call? This way subclasses can potentially override the marshaller used. This enables for example to subclass JdbcBinaryCacheStoreTest and provide a different implementation for getMarshaller() that returns VAM.
