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

             Summary: Error "ISPN006016: Factory 'org.infinispan.server.hotrod.HotRodServer$ToEmptyBytesKeyValueFilterConverter' not found in server" when using remoteCache version 9 against infinispan-server version 8
                 Key: ISPN-8719
                 URL: https://issues.jboss.org/browse/ISPN-8719
             Project: Infinispan
          Issue Type: Bug
    Affects Versions: 9.2.0.CR1
            Reporter: Marek Posolda


Steps to reproduce:
1) Use infinispan server version 8.2.6 (or JDG server 7.1.0) and start it.
{code}
cd JDG_HOME/bin
./standalone.sh
{code}

2) Create sample java project having dependency on latest dependency 9.2.0.CR1 in pom.xml:

{code}
    <dependencies>
        <dependency>
            <groupId>org.infinispan</groupId>
            <artifactId>infinispan-core</artifactId>
            <version>9.2.0.CR1</version>
        </dependency>
        <dependency>
            <groupId>org.infinispan</groupId>
            <artifactId>infinispan-cachestore-remote</artifactId>
            <version>9.2.0.CR1</version>
        </dependency>
    </dependencies>
{code}

3) Add one simple java class based on the tutorial: http://infinispan.org/tutorials/simple/remote/ . The only difference is that I use hotRod protocolVersion 2.5 and calling: 
{code}
remoteCache.keySet().iterator().hasNext()
{code}. I am attaching the class in attachement.

4) Run the class. Seeing exception in both server log and on client-side. 

Server exception

{code}

Indeed, When looking at this line of class RemoteCacheImpl, I see that it references the class, which seem that it was added in HotRodServer version 9. This looks like the cause of the error: https://github.com/infinispan/infinispan/blob/master/client/hotrod-client/src/main/java/org/infinispan/client/hotrod/impl/RemoteCacheImpl.java#L554
