> 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].
