        x.add(123, 124)
        x.and(y)

throws

Should I use Roaring64Bitmap instead?

You would expect better performance with Roaring64Bitmap. Still, this Roaring64NavigableMap bug will be fixed very soon

@blacelle I am curious… What is the rationale for these code sequences to generate what are effectively non-interoperable internal types?

val x = Roaring64NavigableMap()
x.add(123, 124)

val y = Roaring64NavigableMap.bitmapOf(4)

(You don’t have to answer that… but it seems somewhat… interesting…?)
