Java multi-room chat example is broken at least

[PromanSEW]

I downloaded this repo and just run as is, it does not work
Nothing happens after "join room"
Maybe other examples also don't work.
Seems like this repo is abandoned, Play 2.7.3 is here 😞
Please update and fix, if there are any Play devs here

EDIT: Crash

|-ERROR in ch.qos.logback.core.joran.spi.Interpreter@26:52 - ActionException in Action for tag [appender] ch.qos.logback.core.joran.spi.ActionException: ch.qos.logback.core.util.DynamicClassLoadingException: Failed to instantiate type AsyncAppender

I removed logback.xml, but chat is still not working

Hi, @PromanSEW!
I'm sure this repo will also get an our love, but now we work on adoption to Play 3 other modules.

And of course, we are happy if someone keen to provide a pull request 🚀
