Node count fails when Cache.toString() called between @Inject and @Start methods.
---------------------------------------------------------------------------------

                 Key: JBCACHE-1487
                 URL: https://jira.jboss.org/jira/browse/JBCACHE-1487
             Project: JBoss Cache
          Issue Type: Bug
      Security Level: Public (Everyone can see)
    Affects Versions: 3.0.3.GA
            Reporter: Galder Zamarreno

Node count fails when Cache bean is deployed via MC and TRACE is enabled on org.jboss.kernel:

2009-03-03 21:40:51,505 ERROR [AbstractKernelController] (main) Error installing to Instantiated: name=CacheClusterA1 state=Described

MC is printing the cache content in between the two calls to DataContainerImpl.createRootNode(). First
call happens during the @Inject phase and at that point, DataContainerImpl's config has not been set yet
so, getting node numbers is called with usingMvcc=false. This leads to getChildrenDirect() being called
on the root node and this call fails.

See attached logs to compare deployment when TRACE is enabled versus deployment when DEBUG is enabled.
