> Current implementation only allows to return a List with the choices for a given property, action or action parameter.
> It should be improved to allow to return any descendant of java.util.Collection.
> All these cases should be valid:
>          class Customer {
>              @SuppressWarnings("unused")
>             public void someAction(final int x, final long y, final long z) {
>             }
>  
>              @SuppressWarnings("unused")
>             public Collection<Integer> choices0SomeAction() {
>                  return Collections.emptyList();
>              }
>  
>              @SuppressWarnings("unused")
>              public List<Long> choices1SomeAction() {
>                  return Collections.emptyList();
>              }
>             @SuppressWarnings("unused")
>             public Set<Long> choices2SomeAction() {
>                 return Collections.emptySet();
>             }
>          }
