I've been using Dropwizard extensively at work for the last 8 months without touching XML.
But I have to say that XML is often blamed by people who think that complexity would magically vanish. Complexity does not vanish. It can only be shifted around. And it often requires lots of iterations to find an approach that is good enough for everyone. Back in the days, if tooling was right, I did not care about the amount of XML.
