clock demo fails: Error during WebSocket handshake

[ijt]

All of the demos fail on my laptop, probably for the same reason. Here's the error that comes up in the console:

WebSocket connection to 'ws://localhost:1456/websocket/clock1' failed: Error during WebSocket handshake: Unexpected response code: 400

This is on Chrome version 40.0.2214.94 (64-bit).

No error comes up on the server side:
