> From Michal:
> [mlinhard at michal-linhard ~]$ echo -e "cas bad blah 0 0 0\r\n\r\n" | nc localhost 11211 
> SERVER_ERROR org.infinispan.server.core.ServerException: java.lang.NumberFormatException: For input string: "blah" 
> [mlinhard at michal-linhard ~]$ echo -e "cas bad 0 blah 0 0\r\n\r\n" | nc localhost 11211 
> SERVER_ERROR org.infinispan.server.core.ServerException: java.lang.NumberFormatException: For input string: "blah" 
> [mlinhard at michal-linhard ~]$ echo -e "cas bad 0 0 blah 0\r\n\r\n" | nc localhost 11211 
> SERVER_ERROR org.infinispan.server.core.ServerException: java.lang.NumberFormatException: For input string: "blah" 
> [mlinhard at michal-linhard ~]$ echo -e "cas bad 0 0 0 blah\r\n\r\n" | nc localhost 11211 
> SERVER_ERROR org.infinispan.server.core.ServerException: java.lang.NumberFormatException: For input string: "blah" 
> in each case memcached server module should have replied with "CLIENT_ERROR <error>\r\n" 
> as required in: https://github.com/memcached/memcached/blob/master/doc/protocol.txt 
> FYI: original memcached server implementation replies "CLIENT_ERROR bad command line format\r\n" (which is also expected by their test suite, but not required by protocol) 
> Also, verify what Memcached server does with "cas foo 0 0 6 \r\nbarva2\r\n" as opposed to Infinispan Memcached.
