Description

I want to implement a completely asynchronous server, I've used the NHttpServer example but changing the handler to AsyncNHttpServiceHandler.

When throwing this exception from entityRequest():

public ConsumingNHttpEntity entityRequest(HttpEntityEnclosingRequest request, HttpContext context)
throws HttpException, IOException

{ throw new MethodNotSupportedException("method not supported"); }

the DefaultListeningIOReactor shutdowns throwing the following exception:

org.apache.http.nio.reactor.IOReactorException: I/O dispatch worker terminated abnormally

I'm attaching the example to test the error
