Which Java / Scala or .NET web frameworks support changing the source code and instantly starting the ei workflow without lengthy refilling / redeployment procedures?

Question

As far as I can see, the key advantage of dynamic languages ​​like Ruby or Python over Java / Scala / C #, etc. is a "hot" application of your changes in the source code to the running application. What are the frameworks for the JVM or .NET that support the same workflow — apply configuration and source code changes on the fly? Can they also keep track of changes in user configurations and notify the application?

Note. Framework for dynamic JVM / .NET languages ​​such as Grails or Compojure are not available here.

EDIT . I mean not only modifying the body of the method, but also adding / removing methods, fields and classes. What is the average time between the end of editing and monitoring changes in your browser?
