> Issue Type: Bug
> Reporter: Janus Chow
> Assignee: Janus Chow
> Priority: Major

> Fix For: 1.3.0
>
>
> In NodeImpl, the relation of ancestor is decided as follows:
> {code:java}
> @Override
> public boolean isAncestor(Node node) {
> return this.getNetworkFullPath().equals(PATH_SEPARATOR_STR) ||
> node.getNetworkLocation().startsWith(this.getNetworkFullPath()) ||
> node.getNetworkFullPath().equalsIgnoreCase(this.getNetworkFullPath());
> {code}
> The corner case is as follows:
> {code:java}
> Node n1: "/rc"
> Node n2: "/rc1/dc/1.1.1.1"{code}
> The result of n1.isAncestor(n2) is false, while in fact n1 is not n2's
> ancestor.
