IndexOutOfBoundsException thrown by NthComponentFinder when no matching components found

[GoogleCodeExporter]

What steps will reproduce the problem?
1. Instantiate a driver using the NthComponentFinder as a selector
2. Ensure that no components satisfy the specified matchers
3. Observe failure with stack trace below:

Caused by: java.lang.IndexOutOfBoundsException: Index: 0, Size: 0
    at java.util.ArrayList.RangeCheck(ArrayList.java:546)
    at java.util.ArrayList.get(ArrayList.java:321)

    at com.objogate.wl.swing.internal.ProbeRunner.run(ProbeRunner.java:17)

Could be fixed with a check of parentOrOwnerFinder.components() for size before 
converting to a list for return in NthComponentFinder.components()

Slight oversimplification in the steps to reproduce. Turns out that this 
failure occurs when searching for a component within the component matched by 
the NthComponentFinder, when the NthComponentFinder finds no matches.
