Closing of Vert.x instance should be waited on

[Sanne]

We also need to patch DefaultVertxInstance#stop() to actually wait for the shutdown of the instance.

I'm assume we could "just" block in this case? But it would be nice to have a way to do it properly; maybe introducing a reactive flavour of Startable and Stoppable would make sense even for ORM blocking so to allow parallelising some setup/teardown operations.

Blocking sounds fine to me for now.

Introducing new interfaces in ORM doesn't sound like the sort of thing we would do until 6.

[Sanne]

Agreed, blocking will do fine for now.

My second point is more like a question/suggestion: we could explore this in 6 - not sure if it's worth it.

Merged!
