NPE with Amazon Lambda HTTP with JDK 14

[gsmet]

Not sure if this is reproducible easily or if it's a race condition.

I got similar error for Windows JDK 11 JVM Tests and JDK 14 JVM Tests for two different tests.

I don't think that this is amazon lambda specific, I've seen it on Quarkus - Vert.x Web - Deployment test. It seems to be quite non-deterministic, maybe some race condition. I wasn't able to reproduce it locally, only on github's CI action.

It looks like io.quarkus.vertx.web.runtime.RouteHandler.initialize() is not called. I tired this. It passed CI 3 times in row, but it still doesn't meant that it is correct.

@gsmet @matejvasek This should be addressed by #8579. Unfortunately, I can't "force merge" anymore.
