Thomas Neidhart commented on COLLECTIONS-481:
---------------------------------------------
Hi Hollis,
the overloaded methods with two arguments are usually there to avoid the
following warning with Java 1.5 / 6:
Type safety: A generic array of Set<E> is created for a varargs parameter
So we want to keep them for the time being.
In the case of the addComposited(Set[]) method: this should indeed be changed
to varargs.
> remove composite collection methods/constructors made redundant by vararg
> overloads

> Composite* classes overload numerous methods/constructors for the sake of
> convenience. However, many overloads are unnecessary as their functionality
> is covered by vararg implementations. Redundant code should be removed.
