Stefano Bagnara commented on DIRMINA-379:
-----------------------------------------
I tried adding isOpen and isConnected output to the exception by altering the
SocketSessionImpl.setKeepAlive (mina 1.1.8-SNAPSHOT) this way:
public void setKeepAlive(boolean on) {
boolean isConnected = ch.isConnected();
boolean isOpen = ch.isOpen();
try {
ch.socket().setKeepAlive(on);
} catch (SocketException e) {
throw new RuntimeIOException("setKeepAlive error isOpen:
"+isOpen+"/"+ch.isOpen()+" isConnected: "+isConnected+"/"+ch.isConnected(), e);
}
}
The result is this exception:
1513 [AnonymousIoService-8] WARN
org.apache.mina.common.support.DefaultExceptionMonitor - Unexpected exception.

So the channel is OPEN and CONNECTED.
Furthermore I logged the exception from the MINA test failure:

FAILURE!
Tests in error:
testUnbindDisconnectsClients(org.apache.mina.transport.socket.nio.SocketBindTest)
The fact that also the mina test also fails from time to time let me hope that
this is not an issue in my code!
I also tried to alter the order of the setkeepAlive/setReuseAddress as
suggested by Daniel Wirtz in the previous comment but it didn't fix the issue
in my app: I still get the same very exception on the setKeepAlive. The only
difference is that I get the exception few seconds later.
Unfortunately I'm not able to create a small test that always fail. The good
news (or bad??) is that my application fails 100% of the runs.
I'm not sure I understand Alan message: is he saying that we have to report
this to bugs.sun.com and that we cannot do anything to fix this in MINA? Isn't
any workaround we can use to temporarily solve this issue?

> I had to remove the following lines from the SocketSessionImpl constructor:
> this.config.setKeepAlive( cfg.isKeepAlive() );
> this.config.setTcpNoDelay( cfg.isTcpNoDelay() );
> and now it works.
> No matter if I change the configuration to let them return true or false, I
> keep getting the exception if I don't remove the call at all.
