Spring Framework 5.1 is now using reactor-netty 0.8, which comes with breaking changes in its APIs, but also a change in the package names and artifact coordinates.

This migration has been applied to Spring Framework with spring-projects/spring-framework#1845.

@bclozel bclozel added this to the 2.1.0.M1 milestone May 31, 2018

This is in progress:

  • one issue with the TLS client certificate support in HttpClient (the client not sending the certificate to the server); see reactor/reactor-netty#369
  • because HttpServer.Builder no longer exists, we'll have to break the NettyServerCustomizer API. HttpServer is now built with a stateless builder API
  • the new reactor-netty API is missing a way to get the port information, I've opened reactor/reactor-netty#368 and temporarily ignored NettyReactiveWebServerFactoryTests.exceptionIsThrownWhenPortIsAlreadyInUse
  • the reactor-bom needs to publish the new artifact, the new groupId is io.projectreactor.netty instead of io.projectreactor.ipc; see reactor/reactor#646
  • SSL configuration issues with boringssl reactor/reactor-netty#384

Upgrade to Spring Framework 5.1
As of Spring Framework 5.1, we're depending on the Reactor Californium
release train.
Reactor Netty is now at version 0.8 and changed its artifact
coordinates, package names and broke several APIs. Spring Framework is
now up-to-date with those changes and this commit does the same for
Spring Boot.

Note that in that process, the `NettyServerCustomizer` has been changed
since the former `HttpServerOptions.Builder` API is now gone from
Reactor Netty, and we're now relying on immutable server instances
instead of a stateful builder pattern.

See gh-13321
