@twalthr I've addressed most of your comments. Thanks a lot for the
detailed review.
However, now it seems like the Elasticsearch 6.x IT cases are failing, due
to ceased support of Elasticsearch embedded nodes for Java unit tests. I'll
have to look a bit more to see how that can be fixed. Will ping you when that
is addressed.---
