Error on multiple function inheritance.

[gallandarakhneorg]

Let the SARL code:

private static class SynchronizedSetWrapper<E>
     extends SynchronizedCollectionWrapper<E>
     implements SynchronizedSet<E> {
}

The following error is output by the SARL compiler:

The type EmptySet inherits multiple implementations of the method splite
rator() from Iterable and Collection.

See Issue in Xtend.

The temporary workaround until the fix in Xtend is:

		override spliterator : Spliterator<E> {
			(this as SynchronizedSet<E>).spliterator
		}

The current object is casted to the SynchronizedSet because it provides the closest definition of spliterator from the call into the hierarchy call. This approach is compliant with the Java compiler resolution.
