sockjs-error-test

Minimal repro of a SockJS issue where throwing an error during onmessage results in messages being repeated.

Installation

npm install

Running

node index.js

Then launch a browser and go to http://localhost:9999/.

Expected behavior

JavaScript console should say:

Message received: one
Uncaught Error: boom
    [stack trace]
Message received: two
Uncaught Error: boom
    [stack trace]

Actual behavior

JS console says:

Message received: one
Uncaught Error: boom
    [stack trace]
Message received: one
Uncaught Error: boom
    [stack trace]

(i.e. Message received: one appears twice)
