Kind reminder about JDK-8193031

[Сергей Цыпанов]

Hello,

the issue [1] was opened almost two years ago,
but even today Collections.addAll still looks like this:

public static <T> boolean addAll(Collection<? super T> c, T... elements) {
    boolean result = false;
    for (T element : elements)
        result |= c.add(element);
    return result;
}

The most wide-spread collections in Java-world is ArrayList for which Collections.addAll is likely to be slower then Collection.addAll(Arrays.asList).
The same is valid for ArrayDeque and especially for COWList. There's a webrev [2] for mentioned ticket. The whole story begins in [3].

Could the change [2] be done for JDK 13?

Regards,
Sergey Tsypanov
