[PATCH] Inefficient ArrayList.subList().toArray()

[Сергей Цыпанов]

Thanks for quick review!

Indeed, there must be checkForComodification() at the beginning of each method, my bad.

Btw, ArrayList produced by java.util.Arrays.asList() is also RandomAccess and array-based
but has no custom implementation of subList().

Could we apply the same approach for java.util.Arrays.ArrayList?

Sergey
