> If you dont have right guava in classpath you cant query the NonSystemKeyspaces attribute.
i.e. jconsole. can reproduce using Swiss java knife:
> {code}
> # java -jar sjk.jar mx -s localhost:7199 -mg -b "org.apache.cassandra.db:type=StorageService"
-f NonSystemKeyspaces
> org.apache.cassandra.db:type=StorageService
> java.rmi.UnmarshalException: error unmarshalling return; nested exception is: 
> 	java.lang.ClassNotFoundException: com.google.common.collect.ImmutableList$SerializedForm
(no security manager: RMI class loader disabled)
> {code}
> If return a ArrayList or LinkedList or anything in JRE this will be fixed
