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 :

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?
