Failover Mechanism not working with Remote Auxillary Cache

Currently we are using RMI Remote caching and individually i can connect to both the servers indiviadually for example  in client if i set 

jcs.auxiliary.RFailover.attributes.FailoverServers=127.0.0.1:5556

or 

jcs.auxiliary.RFailover.attributes.FailoverServers=127.0.0.1:5555

then caching works fine 

Further i connect my l client to both  the servers as below 

jcs.auxiliary.RFailover.attributes.FailoverServers=127.0.0.1:5556,127.0.0.1:5555 

In this case whenever i cache it always gets added to Primary Server (127.0.0.1:5556) and in case Primary server goes down Caching should be based on Failover server (127.0.0.1:5555) however it is not happening . In case Primary goes down client gets a connection to secondary server (127.0.0.1:5555)  is made as per below logs 

12:42:32.748 [main] INFO org.apache.commons.jcs.auxiliary.remote.RemoteCacheManager - Looking up server //127.0.0.1:5555/org.apache.commons.jcs.engine.behavior.ICacheServiceNonLocal 12:42:32.783 [main] INFO org.apache.commons.jcs.auxiliary.remote.RemoteCacheManager - Server found: Proxy[IRemoteCacheServer,RemoteObjectInvocationHandler[UnicastRef [liveRef: [endpoint:[192.168.56.1:5555](remote),objID:[-55e49f52:1641ca4a40a:-7fff, -6827216959955041134]]]]]

However when i add a new element to JCS Cache in this case it is not reflected so failover seems to be not working as there are no memory hits . Attaching a StackTrace of log from client please provide a fix for this 

 Similar behavior is seen even with JCS 1.3 version 

Below is our configuration for Client , Primary Server and Secondary server
