> Another minor API problem I noticed while digging around. The following Java API methods return a Long as part of their signature, but it's a {{scala.Long}}, not a {{java.lang.Long}}:
> * countByKey
> * countApproxDistinctByKey
> Other similar methods correctly return a Java Long, like countByValue, and the whole Java streaming API.
> Of course, changing this is probably the right thing to do, but also is an API change. I think it's worth fixing up
