I have used Play! on a few projects (my experience coming from the last 10 years of JSP/EJB, JSPX/EJB3/JPA, Struts, Spring, JSF, attempted suicide, etc.) and really enjoyed it. It does a lot of magic and doesn't follow normal Java patterns, but you can look under the covers and the different programming style it uses is easy to grok. If you are a Java dev that is sick of the architect-itus that Java developers typically suffer from, Play will feel great to you. If you are coming from Spring MVC, JSF, Struts2 and any other large-scale framework with a lot of configuration and complex concepts, you will appreciate Play quite a bit more. You can tell the creators are Java devs that played in the Rails arena for a while and brought a lot of that back to the Java world. The mailing list is also quite active and releases are very methodical. Play also works on Google App Engine, (obviously) AWS Elastic Beanstalk, Zenexity's own Playapps cloud hosting[1] and now Heroku... nice to see innovation!
