-----------------------------------------------
For reference -

section 7.2 only describes indexed properties of arrays. So it 'accidentally'
working on List before is no longer always the case (the
IndexedPropertyDescriptor constructor checks for type mismatches between the
positional methods and the overall getter - which now must return a proper
array)
> IndexedPropertyDescriptor not supported for List in Java 8
