----------------------------------------------------------------

The reason seems simple:

{code:java|title=org.jboss.remotingjmx.RemotingConnector.internalConnect}
// Now open the channel
final IoFuture<Channel> futureChannel = connection.openChannel(serviceName, OptionMap.EMPTY);
IoFuture.Status result = futureChannel.await(5, TimeUnit.SECONDS);                 // <-- 5 seconds
if (result == IoFuture.Status.DONE) {
    channel = futureChannel.get();
} else if (result == IoFuture.Status.FAILED) {
    throw new IOException(futureChannel.getException());
} else {
    throw new RuntimeException("Operation failed with status " + result);
}
{code}

As you see there is a hard-coded timeout of 5 seconds. I changed the timeout and now I'm able to connect. Apparently in some cases the connection takes up to 10 seconds! This is so even though the TCP-level connect takes 0.2s -- the 5 s timeout seems to cover _much_ more than just TCP connect.
