[jira] [Created] (HTTPCORE-283) Async server: NPE in
AsyncNHttpServiceHandler when throwing a HttpException from

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 abnormally
at org.apache.http.impl.nio.reactor.AbstractMultiworkerIOReactor.execute(AbstractMultiworkerIOReactor.java:321)

[jira] [Resolved] (HTTPCORE-283) Async server: NPE in
AsyncNHttpServiceHandler when throwing a HttpException from
NHttpRequestHandler.entityRequest
Posted by "Oleg Kalnichevski (Resolved) (JIRA)" <ji...@apache.org>.
[ https://issues.apache.org/jira/browse/HTTPCORE-283?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Oleg Kalnichevski resolved HTTPCORE-283.
----------------------------------------
Resolution: Fixed
This one turned out to be a rather nasty bug. I applied a workaround preventing the i/o reactor from terminating in case of an exception thrown in the #entityRequest method. However, the handler still drops the connection instead of sending a 501 or 500 status to the client, as expected. A proper fix has been applied to the trunk (4.2).
