I've worked with Java for about 17 years now. IMHO Java in 2017 owes a huge debt of gratitude to Ruby, especially Rails and Sinatra. Writing Java REST apps now is immeasurably simpler via things like Ratpack/Dropwizard/Vert.x, using ideas that came from the Ruby world. Even Spring, itself a breath of fresh air, has been forced to play catch-up on occasions.
