If not, you get all exceptions such as: {code} Exception in thread "main" org.infinispan.client.hotrod.exceptions.HotRodClientException: Request for messageId=3 returned server error (status=0x85): java.io.IOException: Unsupported protocol version 100 {code} Example can be found [here|https://gist.github.com/galderz/68302021bd9e957fb0164c1bdd362c3f]. was: When executing tasks, parameters and return types are expected to be marshalled with GenericJBossMarshaller.
