@sgammon I have taken your PR https://github.com/micronaut-projects/micronaut-views/pull/34 updated to:

• use Project Reactor instead of RxJava2
• change the spacing to use 4 spaces instead of 2
• use micronaut nullability annotations intead of javax annotations.

However, they are failing test. Not sure if you can check it out and let me know what am I missing?

@sdelamo I never got notified about this. I'd be happy to take a look.

@sgammon master has changed a lot since. We will need to merge master into this PR. If you want to do another effort towards this, I will review it.
