> Project: Sling
> Issue Type: Bug

> Affects Versions: Scripting Core 2.0.18

> The implementation of ScriptHelper#getServices() creates an Object[] and
> tries to cast it to the generics class. This results in a ClassCastException,
> as an Object[] cannot be cast to a more specific array (i.e. ServiceType[]).
> The solution is to create an array of the correct type and size using
> java.util.reflect.Array#newInstance(), see discussion on stackoverflow[0].
