Under Linux I can't reproduce this exact problem. However, sometimes I get a ConnectException. If I change the line

  bind( false );

into

  bind( true );

and change the line

  ConnectFuture future = connector.connect( addr, new IoHandlerAdapter() );

into

  ConnectFuture future = connector.connect( new InetSocketAddress( "localhost", port ),
                                                                                new IoHandlerAdapter() );

my ConnectException problem seems to go away. It would be great if you could try this under Windows and see if the BindException problem persists. I'm afraid I don't have access to a Windows installation so I can't test it myself. Adding the test method below could be helpful

  public void testALot() throws Exception
  {
    for( int i = 0; i < 100; i++ )
    {
      System.out.println( "Test run " + i );
      testUnbindDisconnectsClients();
    }
  }

You're suggestion with using new InetSocketAddress( "localhost", port) fixed the test case. I applied the change on commit version 369219 here:

http://svn.apache.org/viewcvs.cgi/directory/trunks/mina/core/src/test/java/org/apache/mina/transport/socket/nio/SocketBindTest.java?rev=369219&view=diff&r1=369219&r2=369218&p1=directory/trunks/mina/core/src/test/java/org/apache/mina/transport/socket/nio/SocketBindTest.java&p2=/directory/trunks/mina/core/src/test/java/org/apache/mina/transport/socket/nio/SocketBindTest.java

Thanks!

I still had the problem on Linux Ubuntu 5.0.4.

I fiexd it in maven by adding this parameter in mvn script :
exec "$JAVACMD" \
  -Djava.net.preferIPv4Stack=true \ <<<<<---------------------
  $MAVEN_OPTS \
  -classpath "${M2_HOME}"/core/boot/classworlds-*.jar \
  "-Dclassworlds.conf=${M2_HOME}/bin/m2.conf" \
  "-Dmaven.home=${M2_HOME}" \
  ${CLASSWORLDS_LAUNCHER} $@


Seems that Mina does not like IPV6 !!!

[Emmanuel Lecharny]

downgrade from blocker to major.

[Trustin Lee]

Let's investigate into this issue more and release 0.9.1 without resolving it for now.

[Trustin Lee]

Any updates?

[Niklas Therning]

I cannot reproduce this on my computer. I'm running Ubuntu 5.10 here and as far as I can tell IPv6 is enabled:

Emmanuel, could you verify that this is still an issue for you? If yes, please describe your Java/Linux setup (e.g. is only the lo network interface available).

Does anyone else have problems with the SocketBindTest?

[Trustin Lee]

I tested both on Debian Linux and on Windows XP professional, but I couldn't reproduce the problem, either.

It would be nice if we can mark this issue as 'can't reproduce' unless there's any objection.
