--------------------------------------

             Summary: Remote server tasks still expect GenericJBossMarshaller
                 Key: ISPN-8814
                 URL: https://issues.jboss.org/browse/ISPN-8814
             Project: Infinispan
          Issue Type: Bug
          Components: Marshalling, Tasks
    Affects Versions: 9.1.6.Final, 9.2.0.CR2
            Reporter: Galder Zamarreño
            Assignee: Gustavo Fernandes


When executing tasks, parameters and return types are expected to be marshalled with GenericJBossMarshaller. 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].

A workaround is to have separate RemoteCache instances, built with different configuration used for data versus task execution, [example|https://gist.github.com/galderz/d1cc02d520352a6af036ed0fc677e208].
