Description Matej Čimbora 2014-11-12 14:16:52 UTC 
Tested version: ER3, server

When <backups><backup site="XYZ"/></backups> is not present in configuration of a given cache, "site" CLI operations are still available on the node. However, their usage leads to NPEs being thrown, e.g.

Comment 3 Matej Čimbora 2014-12-04 11:11:33 UTC 
I confirm the issue has been fixed by displaying appropriate message. 

One more NPE found on consumer site after invoking push operation on producer site. Occurs when corresponding cache does not exist there (either with the same name as the main cache or specified via <backup-for> option).

Producer site CLI:

Unable to pushState to 'LON'. org.infinispan.commons.CacheException: Problems invoking command.

Consumer site log:
