REPEATABLE_READ inconsistent with write skew disabled
-----------------------------------------------------

                 Key: JBCACHE-1493
                 URL: https://jira.jboss.org/jira/browse/JBCACHE-1493
             Project: JBoss Cache
          Issue Type: Bug
      Security Level: Public (Everyone can see)
          Components: Locking
    Affects Versions: 3.0.3.GA
            Reporter: Manik Surtani
            Assignee: Manik Surtani
             Fix For: 3.1.0.GA


Inconsistent in that with a put(), we have the last tx winning and overwriting state, which is allowed if write skew is disabled.  

If we have a concurrent put() and removeNode(), this is a problem since the removeNode() would only remove a node read earlier in the same transaction and not the new, updated node.

E.g.,:

cache.put("/a", "k", "v");
tx.begin();
cache.get("/a");
tx.suspend();
cache.put("/a", "k", "v2");
tx.resume();
cache.removeNode("/a");
tx.commit();
// node still exists!!
