> If you pass a path that doesn't start with '/' to INode.getPathComponents, it throws a NullPointerException. Instead it should throw IllegalArgumentException to make it clear that absolute paths are required in this code.
> The attached patch fixes this, clarifies, the javadoc, and adds a test case.
