Jooby SSE Server

A simple server-sent events server that supports multiple concurrent clients, and properly handles client-side disconnects. Uses Jooby 2.

Apache Camel as SSE consumer

TLDR — Camel can't be used as an SSE consumer.

Documenting this here since I created this server to test if Camel can be used as an SSE consumer.

Camel doesn't seem to have a component for this (as at version 3.9.0) and the built in HTTP support does not seem to nicely handle it — there is no support for from('http://...') and using to('http://...') will not return a response until the response stream closes (which is entirely reasonable).

Tested with both the http and ahc components.

I know that Camel does work as a WebSocket consumer, so there is not a lot of point in spending more time on this.
