Following code executes silently on b88 - NullPointerException is not thrown:

import java.util.PrimitiveIterator;
import java.util.function.Consumer;
import java.util.function.IntConsumer;

public class PrimitiveIteratorForEachRemaining implements PrimitiveIterator.OfInt {

    public static void main(String argv[]) {
        new PrimitiveIteratorForEachRemaining().forEachRemaining((IntConsumer) null);
        new PrimitiveIteratorForEachRemaining().forEachRemaining((Consumer<Integer>) null);
    }
    @Override
    public int nextInt() {
        return 0;
    }

    @Override
    public boolean hasNext() {
        return false;
    }

}

Similar thing does happen for both PrimitiveIterator.OfLong and PrimitiveIterator.OfDouble as well.

According to forEachRemaining(IntConsumer) spec NPE should be thrown.

I wonder if spec should specify that NPE is thrown when forEachRemaining(Consumer) is passed a null as a consumer?

The code is attached for your convenience.
