How to achieve timeout handling in blocking DatagramChannel without using selectors

I get a feeling that I am missing something really obvious here.

The overall structure of my system makes me want to use a blocking DatagramChannel without Selectors, in order to keep things simple. I am trying to achieve timeout handling by setting a timeout on the socket, but this seems to have no effect.

This pseudoized code gives a hint of what I am trying to achieve.

DatagramChannel channel = DatagramChannel.open();
channel.socket().bind(some address);
channel.socket().setSoTimeout(3000);
channel.send(outBuffer, peerAddress);

channel.receive(inBuffer);

On the other side, I have a UDP server that gives five quick responses, and then, for testing purposes, delays about five seconds before delivering the sixth response.

The delay does not trigger a SocketTimeoutException. Why is that? The timeout set on the socket does not seem to be taken into consideration when calling channel.receive.
