Not sure why they'd write all these libraries from scratch instead of just reusing something like Play or Dropwizard that are more used and thus probably better supported and have more of the kinks worked out. Wish they'd explain that up front.

Have you tried play framework? Because it installs a lot of libraries and let's not talk about performance.

I'm using the Play framework. I run it on dedicated hardware, so the few extra MB of disk space doesn't bother me.

I know you don't like talking about it, but do you have something to share about its performance?

[betimsl]

It's not a matter of a few extra MB, but number of libraries, more libraries equals more bugs equals more problems.

I'm not saying only play has this problem, almost all java frameworks from the time of play have similar properties.

On the other hand, it is slow, embarrassingly slow (try running it on RPi). For me it's really complicated as well. You have routes file (which is redundant). Templating language forces you to write Scala which then uses a Scala compiler to compile which it is really slow (even Martin said it's slow). It's a vicious circle.
