             Summary: Remote Cache Store does does't work properly in compatibility mode
                 Key: ISPN-6883
                 URL: https://issues.jboss.org/browse/ISPN-6883
             Project: Infinispan
          Issue Type: Bug
          Components: Loaders and Stores
    Affects Versions: 9.0.0.Alpha3
            Reporter: Sebastian Łaskawiec
            Assignee: Tristan Tarrant


Currently we can't use Remote Cache Store for Caches populated using REST with compatibility mode.

The configuration for source cache looks like the following:
{code}
<distributed-cache name="default" mode="SYNC" segments="20" owners="2" remote-timeout="30000" start="EAGER">
  <locking acquire-timeout="30000" concurrency-level="1000" striping="false"/>
  <transaction mode="NONE"/>
  <compatibility enabled="true" />
</distributed-cache>
{code}

Destination cache:
{code}
<distributed-cache name="default" mode="SYNC" segments="20" owners="2" remote-timeout="30000" start="EAGER">
  <locking acquire-timeout="30000" concurrency-level="1000" striping="false"/>
  <transaction mode="NONE"/>
  <compatibility enabled="true" />
  <remote-store cache="default" hotrod-wrapping="true" read-only="true">
    <remote-server outbound-socket-binding="remote-store-hotrod-server" />
  </remote-store>
</distributed-cache>
{code}

With the configuration above, when performing [Rolling Upgrade|http://infinispan.org/docs/stable/user_guide/user_guide.html#steps_2] procedure I get:
