[undertow-dev] exchange.getResponseSender().send issues

[Bill O'Neil]

You shouldn't need to be setting the content length manually with that API.

I agree with the exception, Stuart might have some thoughts on that. There
was another discussion about hooking in different loggers to the default
exception handler as well as an easier way to override it. This issue could
be related to that?
