Async server: NPE in AsyncNHttpServiceHandler when throwing a HttpException
from NHttpRequestHandler.entityRequest
------------------------------------------------------------------------------------------------------------------
Key: HTTPCORE-283
URL: https://issues.apache.org/jira/browse/HTTPCORE-283
Project: HttpComponents HttpCore
Issue Type: Bug
Components: HttpCore NIO
Affects Versions: 4.1.3
Reporter: Isaac Cruz Ballesteros
Attachments: NHttpServer.java
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
