> Consider the following piece of code
> {code:title=JobInProgress.createCache()|borderStyle=solid}
> Node node = jobtracker.resolveAndAddToTopology(host);
> for (int j = 0; j < maxLevel; j++) {
>           node = JobTracker.getParentNode(node, j);
>           .....
> {code}
> With {{maxLevel > 2}} the caches will be created in the following order
> ||j||node-level||
> |0|0|
> |1|1|
> |2|3|
> |3|6|
> which is not as desired.
