data consistency issue with ReadUncommited
------------------------------------------

                 Key: JBCACHE-1364
                 URL: http://jira.jboss.com/jira/browse/JBCACHE-1364
             Project: JBoss Cache
          Issue Type: Bug
      Security Level: Public (Everyone can see)
    Affects Versions: 1.4.X
            Reporter: Mircea Markus
         Assigned To: Manik Surtani


Scenario
    * tx1 starts and create /a/b/c (results in following locks being acquired: rl for a and b and wl for c)
    * tx2 starts and adds a key value under /a/b (acquires a WL on b, as for ReadUncommited WL does not wait for RL to be released)
    * tx2 commits (so the key-value tx2 added under /a/b is there, correctly)
    * tx1 rollabcks  FAILURE! - this will also delete the /a/b committed at the previous step

the problem is that when creating a structural node (e.g. a and a/b) a RL is acquired. This is not correct, a WL should be acquired instead. (on 2.x series that's how it goes).
 

test added to reproduce the issue: IsolationLevelReadUncommitedTest (on 1.4.X branch)
