Looks like simpler Java frameworks are on the rise now (http://www.pippo.ro/, http://sparkjava.com/, http://www.rapidoid.org/)

I'm not sure I would consider it on the rise or a recent trend, considering we had a all sorts of these things over the past 6-7 years already (and more, if you include other JVM languages in the mix).

It sure is nice to see a bit of competition though. But I'm a bit afraid of too much fragmentation and proliferation, when sometimes fixing or improving good frameworks might be time better spent. It was (and still is) a bit annoying when every week brings about a dozen new web frameworks, a new UI toolkit, a new stack acronym, etc...

Oh well... I guess you can't really tell what's time well spent, and you can't really product how frameworks will compete and improve evolutionarily.

About time. Since the advent of java 8 the platform is rejuvenating. This is clearly an example of that.

Is it? You could write a sinatra-like microframework in java a long time ago (I did). Just use methods instead of lambdas.

Though, perhaps 8 has inspired framework developers, and - more importantly! - attracted a more adventurous userbase?

At least I feel like. 8 brought some really needed upgrades (for example we have a new form of multiple inheritance). It is not perfect but I think with the Stream api and the lambdas they simplified things enough for people to at least give it a try.

> attracted a more adventurous userbase?

That statement seems accurate without "a more adventurous" - I think with Java 8 more people are using Java because they want to instead of because they have to.

e.g. professionally I've used Java more than any other language, it's hands down the language I'm most familiar/comfortable with, yet when I start a side project for myself I've never considered using Java (usually using Ruby or Scala). With Java 8 removing many warts and bringing in a lot of great improvements I'd actually consider using it for a side project.

You can add this one to the list: http://www.takes.org/

As well as Jodd [0], Play [1] and many more [2, 3].

Play is not minimalistic like Jodd, Spark, Rapidoid, Pippo, Take (that is the name even though the domain name is takes.org) are.

Very happy to see this trend catch up with Java.

I can vouch for Dropwizard. Have used in a few tier-1 services and it has worked out fabulously well.
