CXF http-jetty transport do not call the jetty server engine shutdown when the
server stop
------------------------------------------------------------------------------------------
Key: CXF-865
URL: https://issues.apache.org/jira/browse/CXF-865
Project: CXF
Issue Type: Bug
Components: Transports
Affects Versions: 2.0
Reporter: willem Jiang
It appears that stopping the server in CXF is not shutting down the Jetty
engine, which causes my application to hang because Jetty's threads are still
blocking on the server socket accept. After a shutdown, I still see Thread
[btpool0-0 - Acceptor0 [EMAIL PROTECTED]:10001] (Running).
I have a simple test application pasted below that can reproduce the problem.
At this point I had to add some calls to get the destination and cast it to a
Jetty specific class to get things to exit. Is there a better way to do this?
Is there something I'm not configuring correctly? Any help is appreciated.
This is under Java 1.5 with CXF 2.0. Jetty is being included from the CXF libs
directory.
package org.mpilone.cxftest;
import java.io.IOException;
import org.apache.cxf.endpoint.Server;
import org.apache.cxf.frontend.ServerFactoryBean;
public class CxfJettyTest
{
public void doIt()
{
System.out.println("Running test method");
}
public static void main(String[] args) throws IOException
{
// Create an Service and Server
ServerFactoryBean serverFactory = new ServerFactoryBean();
serverFactory.setServiceClass(CxfJettyTest.class);
serverFactory.setServiceBean(new CxfJettyTest());
serverFactory.setAddress("http://localhost:10001/RemoteApi";);
Server mServer = serverFactory.create();
mServer.start();
System.in.read();
mServer.stop();
// Adding these lines allows the application to exit, but
// WARNING: EXCEPTION
// java.nio.channels.ClosedChannelException
// log statements are produced.
// JettyHTTPDestination jettyDest = (JettyHTTPDestination)
// mServer.getDestination();
// JettyHTTPServerEngine jettyEngine = (JettyHTTPServerEngine)
// jettyDest.getEngine();
// jettyEngine.shutdown();
System.out.println("Exiting");
}
}
If you looking into the code you will find there is a note in the
JettyHTTPServerEngine's removeServant(URL url)
/* Bug in Jetty, we cannot do this. If we restart later, data goes
off
* someplace unknown
if (servantCount == 0) {
try {
....
}*/
I just added the shutdown engine's code below the comments and tested it
against the systest. There were some tests (such as ws.rm , mtom )failed.
It looks like if we shutdown the engine, when the engine start again , the
engine can not get the request info again , specially the http keep alive
message.
Current I can't reproduce this bug by adding the unit test which simply calls
start and shutdown method the JettyHTTPServerEngine.
It may take some time to resolve this issue.
