Rollback fails when triggered by a non-successful operation on a non-existent node
----------------------------------------------------------------------------------

                 Key: JBCACHE-1363
                 URL: http://jira.jboss.com/jira/browse/JBCACHE-1363
             Project: JBoss Cache
          Issue Type: Bug
      Security Level: Public (Everyone can see)
    Affects Versions: 2.2.0.CR2, 2.2.0.CR3
            Reporter: Jason T. Greene
         Assigned To: Manik Surtani
            Priority: Critical
             Fix For: 2.2.0.GA


It seems that most of the key commands attempt to rollback even if there is nothing to rollback.  

In the following case the RemoveKeyCommand.rollback() method throws an exception when the node does not exist, this 
in turn leads to aborting the entire rollback, so all other changes persist. Further there is no exception thrown to the calling app.

org.jboss.cache.Cache cache = cache_.getCache();
cache.start();
cache.put("/blah", "test", "correct");
tx_mgr.begin();
cache.put("/blah", "test", "wrong");
cache.remove("/blah/blah", "non-exist");
tx_mgr.rollback();
assertEquals("correct", cache.get("/blah", "test")); // Ends up being wrong
