[jira] Created: (DIRMINA-435) NullPointerException in
IoServiceListenerSupport
NullPointerException in IoServiceListenerSupport
------------------------------------------------
Key: DIRMINA-435
URL: https://issues.apache.org/jira/browse/DIRMINA-435
Project: MINA
Issue Type: Bug
Components: Core
Affects Versions: 1.1.2
Environment: WinXP SP 2
java version "1.5.0_11"
Java(TM) 2 Runtime Environment, Standard Edition (build 1.5.0_11-b03)
Java HotSpot(TM) Client VM (build 1.5.0_11-b03, mixed mode, sharing)
Reporter: Matthew Phillips
This is an odd one, since it occurs on WinXP and not on Mac OS X. The error was seen under 1.5, but also occurs on 1.6. I see the following NPE :
-----
Exception trace:
java.lang.NullPointerException
at java.util.concurrent.ConcurrentHashMap.hash(Unknown Source)
at java.util.concurrent.ConcurrentHashMap.putIfAbsent(Unknown Source)
at org.apache.mina.common.support.IoServiceListenerSupport.fireSessionCreated(IoServiceListenerSupport.java:152)
at org.apache.mina.transport.socket.nio.SocketIoProcessor.doAddNew(SocketIoProcessor.java:135)
at org.apache.mina.transport.socket.nio.SocketIoProcessor.access$300(SocketIoProcessor.java:44)
at org.apache.mina.transport.socket.nio.SocketIoProcessor$Worker.run(SocketIoProcessor.java:444)
at org.apache.mina.util.NamePreservingRunnable.run(NamePreservingRunnable.java:39)
at java.util.concurrent.ThreadPoolExecutor$Worker.runTask(Unknown Source)
at java.util.concurrent.ThreadPoolExecutor$Worker.run(Unknown Source)
at java.lang.Thread.run(Unknown Source)
------
The NPE is being caused by IoSession.getServiceAddress () returning null, which then bombs the attempt to use it as a key in the map (IoServiceListenerSupport:151):
SocketAddress serviceAddress = session.getServiceAddress(); // null
// Get the session set.
Set<IoSession> s = new IdentityHashSet<IoSession>();
Set<IoSession> sessions = managedSessions.putIfAbsent(serviceAddress,
Collections.synchronizedSet(s));
This has me stumped. Can anyone help?

------------------------------------------
Actually, a better way to do this would be to run just the test that I'm seeing fail.
If you do an svn update and run "cd java/server && ant test-federation" (note directory has changed since last time) and see what happens.

Matthew Phillips commented on DIRMINA-435:
------------------------------------------
Sorry, it seems I've broken the tests, I'm seeing that intermittently too. Let me see if I can fix those first.
I was under the impression the NPE was being caused by using a null key in the hash map: calling hash () on that was causing the exception. Since there are no line numbers, that was only my best guess though. You think it was something else?

Matthew Phillips commented on DIRMINA-435:
------------------------------------------
It is reproducible, and happens all the time, no significant load.
I don't even know where to begin trying to create a test case, but if you're willing to grab the project from SVN at https://avis.svn.sourceforge.net/svnroot/avis/trunk and run the test case in server/src/test/org/avis/federation/JUTestFederation.java (JUnit 4.1), you should find it fails on WinXP. If you have ant 1.7, "cd server && ant tests" will do it (I'm running it in JUnit under Eclipse).
I've run the exact same test on Mac OS X on both a G4 Powerbook and an Intel Mac Pro, and it runs fine there. It also runs on an (old'ish) FC3 Linux box.
Like I said, very odd.

Trustin Lee commented on DIRMINA-435:
-------------------------------------
What's really odd is that the NPE is thrown from ConcurrentHashMap.hash(). The hash() method has nowhere to throw such an exception because its purely an arithmetic function. If the returned IoSession is null, the NPE should be thrown from putIfAbsent() method.
Could you try to upgrade the JRE? Let me run the tests too soon.

-------------------------------------
Hi Matthew, thanks for tracking down this problem for us. I really appreciate it. I have made some change in SocketConnector so it doesn't create a session as long as finishConnect() returns false. Please check out the latest source code, give it a try and let me know if it fixes your problem or not, because my fix is different from yours.

[jira] Commented: (DIRMINA-435) NullPointerException in
IoServiceListenerSupport
Posted by "Matthew Phillips (JIRA)" <ji...@apache.org>.
[ https://issues.apache.org/jira/browse/DIRMINA-435?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel#action_12548063 ]
Matthew Phillips commented on DIRMINA-435:
------------------------------------------
This problem just bit me again, so I embarked on on some tracing. It happens on WinXP when trying to connect to an overseas host, so it may be triggered by the extra latency (the same code works fine for most other cases).
What seems to be causing it is MINA's SocketConnector class assuming that SocketChannel.finishConnect () will always return true, i.e. return when the connection is established. This is false in my case, resulting in a null remote address (SocketChannel.socket().getRemoteSocketAddress(), see line 334), which triggers the NPE in the worker.
Using the changes in the patch I'll attach shortly fixes this and established a connection successfully. These changes effectively poll finishConnect() for up to 10 seconds, throwing an exception if it ultimately failed.

> This is an odd one, since it occurs on WinXP and not on Mac OS X. The error was seen under 1.5, but also occurs on 1.6. I see the following NPE :

> The NPE is being caused by IoSession.getServiceAddress () returning null, which then bombs the attempt to use it as a key in the map (IoServiceListenerSupport:151):
> SocketAddress serviceAddress = session.getServiceAddress(); // null
> // Get the session set.
> Set<IoSession> s = new IdentityHashSet<IoSession>();
> Set<IoSession> sessions = managedSessions.putIfAbsent(serviceAddress,
> Collections.synchronizedSet(s));
> This has me stumped. Can anyone help?
