for discussion: allow class derivatives of OpenAPI class DocumentedHandler

[RalphSteinhagen]

By default Kotlin classes are final. would it be conceivable to open some of Javalin's classes, notably the class DocumentedHandler(...) in package io.javalin.plugin.openapi.dsl, to allow for further class extensions
or -- alternatively -- convert this to a public interface?

The specific use-case would be to provide a more meaningful source class implementation/package location information, for example, in the RouteOverviewPlugin, and other debugging cases by overwriting the toString() function:

(note the io.javalin.plugin.openapi.dsl.DocumentedHandler.class string that could hide any source implementation location).

This would help in debugging service implementations but also allow further user-specific custom extensions. Food for thought.

And as always: keep up the good work!

I'm generally all for everything being open unless there's a strong reason not to. In fact, this is one of my primary complaints about Kotlin, I think sealed as default is a very poor choice. That said, it obviously does reduce the amount someone maintaining a library has to support.

I haven't yet had a use case for modifying the DocumentedHandler, but I am always for opening something.

[RalphSteinhagen]

OK, I'll make a PR then.

Thanks @RalphSteinhagen ! There was no reason it was non-open (other than it being the default).
