A DESCRIPTION OF THE REQUEST :
To add an array to a Collection we can use Collections.addAll(Collection<? super T> c, T... elements). It should be possible to add an array of elements directly to a collection.

JUSTIFICATION :
This extension improves the readability and clearity of code.

addAll(collection,array)

vs

collection.addAll(array)

EXPECTED VERSUS ACTUAL BEHAVIOR :
EXPECTED -
Collection.add(T ...elements) should behave exactly as Collections.addAll(Collection<? super T> c, T... elements).

---------- BEGIN SOURCE ----------
 Collection<String> c = new ArrayList<String>();
 c.addAll( "a","b","c" );
        
assertThat(c).containsExactly("a","b","c");
---------- END SOURCE ----------
