    Cache data seems invalid/corrupted when reading via memcached endpoint

      Hi all,

       

      I'm using infinispan-server-5.3.0.CR2 from different client interfaces (Java and c++) so I'm required to use both hotrod and memcached endpoints.

      I was recently advised to use the <compatibility enabled="true"/> and it helped to share my cache data across endpoints.

       

      There are still some issues however.

       

      If I insert the following cache entry from java using hotrod:

       

          RemoteCacheManager rcm = new RemoteCacheManager("devhost:11222");

          RemoteCache rc = rcm.getCache("memcachedCache");

          rc.put("hotrod","a_nice_value");

       

      Then I can show the key via the REST interface without problems:

       

      bash-3.00$ telnet devhost 8080

      Trying 10.10.114.16...

      Connected to devhost.

      Escape character is '^]'.

      GET /rest/memcachedCache/hotrod HTTP/1.0

       

      HTTP/1.1 200 OK

      Server: Apache-Coyote/1.1

      Connection: close

       

      a_nice_value

       

      However if I try the same using the memcached interface I seem to get some junk or header or other binary data before the actual value:

       

      bash-3.00$ telnet devhost 11211

      Trying 10.10.114.16...

      Connected to devhost.

      Escape character is '^]'.

      get hotrod

      VALUE hotrod 0 19

      ’t

         a_nice_value

      END

       

      Is there something wrong with the memcached interface or do I need some other configuration?

       

      If you require more background information please check this thread where I got the tip to enabled compatibility mode: https://community.jboss.org/thread/229675

       

      Thanks,
