What is the current behavior?
In AppData.more(String[] path), when the path contains at least two elements, the method returns a String[] containing the different elements starting from the index 2 and stopping at the index length - 1. The issue is that the last index is excluded so the last element is not returned.

What is the new behavior (if this is a feature change)?
The method now returns up to the index length so that the last element is also returned
