Subscription to second channel overrides the first subscriber

[kuceram]

This error happens when you send headers object to subscription method like this:

var headers = {'Authorization': `Bearer 123`};
var subscription1 = client.subscribe(destination1, callback1, headers);
var subscription2 = client.subscribe(destination2, callback2, headers);

If you do the second subscription you loose the reference to the first one (callback destination1 is never called). This issue came due to the fact that you break the atomicity rule:

You should not manipulate object that are coming from outside.

Interesting, I suppose calling subscribe with a clone of headers fix the issue temporary, does it?

[kuceram]

Yes it does. But I would suggest to do a clone internally within the subscribe method as method user might not be aware of this. It is also hard to debug this inconvenient.

@kuceram is that ok for you?

[kuceram]

Hi, sorry for late respond. I will check it out as soon as possible and let you know. :-)

Works fine, now...
