I'm getting this exception when I configure an infinispan cache with remote-store:

For this to work, Infinispan subsystem (CacheAdd class) should now set different properties for the RemoteCacheStore. It now sets "infinispan.client.hotrod.server_list" directly as a property while it should most likely set "HotRodClientProperties" as a key and a Properties object (which would contain "infinispan.client.hotrod.server_list" as a key and proper value as a value) as a value.

See http://docs.jboss.org/infinispan/5.1/apidocs/org/infinispan/loaders/remote/RemoteCacheStoreConfig.html

...hope that helps
