[Quarkus 1.6.1.Final] platform-http: dev mode breaking with log "Request has already been read"

[aldettinger]

From a shell, execute:
watch -n 0.1 http :8080/count <<< '{count: 20}'

From another shell:
Create a simple http-platform route from("platform-http:/count").setBody(constant("count !"));
mvn quarkus:dev

Modify the route definition and save, quarkus hot-reload is triggerd but now the route crash from time to time with below stack trace:

Must be an occurence of quarkus#9693, let's integrate the fix when available.

[aldettinger]

quarkus#9693 should be fixed in quarkus 1.7 1.6.1.Final. Let's follow up on that one.

[aldettinger]

So, it really was an occurrence of quarkus#9693. Since quarkus 1.6.1.Final, I couldn't reproduce anymore.
