fix for resource bundles - rhq server

It should fix: https://bugzilla.redhat.com/show_bug.cgi?id=878919

Finally I was able to see particular caches. After issuing some operations via CLI I can see live-changing cache statistics. 

What still I can't --> issue ANY operation on cache. Button "Operations" after right click is grey, therefore we are not able to test X-site functions. I guess  this is not integrated yet - or should be?
