Scalatra 2.3.1 Swagger breaking change?

Hi guys,

When I attempt to use Scalatra 2.3.1+ with Swagger according to what's currently in the docs, I get the following error:

[info] Compiling 3 Scala sources to /Users/dave/workspace/foss/scalatra-website-examples/2.3/swagger-example/target/scala-2.11/classes...
[error] /Users/dave/workspace/foss/scalatra-website-examples/2.3/swagger-example/src/main/scala/org/scalatra/example/swagger/FlowersController.scala:14: class FlowersController needs to be abstract, since method render in trait JsonMethods of type (value: org.json4s.JValue)(implicit formats: org.json4s.Formats)scala.text.Document is not defined

[error] class ResourcesApp(implicit val swagger: Swagger) extends ScalatraServlet with NativeSwaggerBase
[error]       ^
[error] two errors found

@rossabaker @casualjim @seratch any idea what fixes these? I'd like to document the fix, currently all our Swagger docs will fail for anyone who generates a project and tries to follow the docs.

To repro it, just change the dependency to to 2.3.1 in the Swagger project in the repo scalatra/scalatra-website-examples.

Aha. Sorry for the noise. json4s 3.2.11, obviously, is the answer here.
