* TODO: cpovirk - Is this an issue anywhere anymore? It looks to have been fixed for Java 8
   * (https://bugs.openjdk.org/browse/JDK-7121314) and before Lollipop
   * (https://r.android.com/47508). We *would* need to worry for J2KT, whose own concurrency support
   * is evolving (b/381065164, b/458160722), but this class is @J2ktIncompatible.
   *
   * 2. The superclass toArray() method declares the more general return type `@Nullable Object[]`,
