I have a similar problem, which may could have the same cause. I am using play 2.6.11 and swagger-play 1.6.0 It looks like the newInstance method fails for the class SwaggerScalaModelConverter for some reason. The problem occurs after adding the following dependency to my build.sbt file: libraryDependencies += "com.auth0" % "java-jwt" % "3.3.0" After removing the line, swagger-play works again. There have been no other changes to my codebase beside of this line.
