Session created with non-existent service
-----------------------------------------
Key: DIRMINA-273
URL: http://issues.apache.org/jira/browse/DIRMINA-273
Project: Directory MINA
Issue Type: Bug
Components: Core
Affects Versions: 1.0, 0.9.5, 0.9.4
Environment: Windows 2000 SP4, Java 1.5.0_08
Reporter: Raman Gupta
Attachments: MinaConnectTest.java
On Windows 2000, when attempting to connect to a service on a port where no
service is running (either locally or remotely), Mina will sometimes create and
open a session instead of throwing an IoException. This session is of course
unusable, and when attempting to use it an exception is thrown (the following
exception from Mina 0.9.4):
java.nio.channels.NotYetConnectedException
at
sun.nio.ch.SocketChannelImpl.ensureWriteOpen(SocketChannelImpl.java:129)
at sun.nio.ch.SocketChannelImpl.write(SocketChannelImpl.java:294)

org.apache.mina.transport.socket.nio.SocketIoProcessor.doFlush(SocketIoProcessor.java:480)

org.apache.mina.transport.socket.nio.SocketIoProcessor.access$500(SocketIoProcessor.java:41)
at
org.apache.mina.transport.socket.nio.SocketIoProcessor$Worker.run(SocketIoProcessor.java:568)
This is reproducible within a few seconds with the attached test case on
Windows 2000 on Mina 0.9.4 and Mina 1.0.0. I also attempted to reproduce this
on Linux 2.6.17 but was unable to.
I have attached two test cases, one MinaConnectTest and one MinaConnectTest10,
the former is for 0.9.4 and the latter is for 1.0.0 -- the only change is the
exception caught.
Though the attached test case fails uses only localhost (to avoid DNS
complications), the test case also fails if a remote host is used. I tested
with a remote host running Solaris 8 from a Windows client.
Lastly, netcat in a tight loop was used concurrently with the test to verify
that the port was indeed refusing connections.
