Found the bug.  Added more unit tests to the optimistic test suite to include this kind of error as well.

> Manik, I am not assigning this Jira to any release. It is your call to fix it either in ALPHA2 or BETA1. Basically, my o.jo.c.pojo.optimistic.CachedListTest failure can be attributed to this test case:
>    public void testFailure1() throws Exception
>    {
>       log.info("testFailure1() ....");
>       UserTransaction tx = getTransaction();
>       org.jboss.cache.Fqn f = new org.jboss.cache.Fqn("/person/test2");
>       tx.begin();
>       cache.getCache().put(f, "test", "test");
>       tx.commit();
>       tx.begin();
>       cache.getCache().removeNode(f);
>       cache.getCache().put(f, "test", "test");
>       tx.commit();
>    }
> For optimistic locking and it produces the following error:
> org.jboss.cache.CacheException: Unable to set node version for //person/test2, node is null.
