I've upgraded our master build to Jackson 2.9 PR1: no compatibility issues so far.

Let's see whether there's anything 2.9-specific that we can support eventually...

Pull request created to be reviewed by Arjen Poutsma for the Spring MVC side.

I have added support for returning 5xx status code instead of 4xx for InvalidDefinitionException for Spring MVC and Spring WebFlux (functional and annotation-based).

Notice that since InvalidDefinitionException is Jackson 2.9+ it raises the Jackson minimum requirement to this version.

I resolve this issue as complete since we are already on 2.9.0.pr2 and I expect no new features to adapt to (expect on Reactive side but their is other issues for that). We will just have to upgrade to 2.9.0 when available.

I've upgraded the build to Jackson 2.9 PR3 now, assuming that's what we're going to release against next week.

@Juergen is it possible to upgrade jackson 2.9.x if we are using spring 4.x ?

As far as I'm aware, there are no known incompatibilities between Spring Framework 4.3.x and Jackson 2.9.x. We'd certainly be willing to address those if we learn about any such issues. However, first-class Jackson 2.9 support - including special translation of InvalidDefinitionException is a Spring Framework 5.0+ feature.

So effectively, Spring Framework 4.3.x - as our long-term support branch - is compatible with Jackson 2.6 up until 2.9, and we'll keep it compatible with Jackson 2.9.x.
