[undertow-dev] Undertow jboss logging redirect to logback log file and console

[Bill O'Neil]

2. As long as you are ok with making every route a blocking route that
should be fine. I did the same thing.

https://github.com/undertow-io/undertow/blob/master/core/src/main/java/io/undertow/server/handlers/BlockingHandler.java#L52

I use the blocking handler above before passing to the exception handler.
Your return seems out of place and it also never calls startBlocking(). I'm
not sure how important that is.
