This is a porting of TypeSafe's Reactive Stock example to Quasar Actors and Comsat Web Actors. Run on Jetty embedded servlet container plus its WebSocket module.

1. ./gradlew run.
2. Open http://localhost:8080 in Firefox.
3. Play with it.

• The Java implementation is almost as compact as the half-Scala original one.
  • ...And much easier to understand.
• Quasar Actors are based on Quasar's lightweight threads or fibers which make all the code is code straightforward, sequential imperative style.
  • No declarative-functional-monadic-async programming is forced down your throat just to work around JVM threads' heavy footprint.
• Since calls are (fiber-)blocking and full control flow language can be used around them, no tick message is needed: just use the straightfoward blocking receive with a timeout.
• By default Web Actors automatically assign a new actor to a request or WebSocket connection, which can be configured for automatic termination upon connection closing with a simple watch call.
  • So, supervision isn't really necessary and Quasar doesn't make it mandatory (it is there just to showcase it).
• Actors and Web Actors do just one thing well: everything is conf- and JSON-library agnostic, you're not forced into a full-blown lock-in web framework.
• 100% Servlet compatible, no need to run a non-standard embedded server if you don't want to.

• Currently generated web resources are just copied: add build steps from original CoffeeScript and LESS source files.
• Do away with the comsat-testutils dep.
• Add Capsule-based deployment.
