Just noticed, the POST packet of Bitbucket is like:

{"test": true}

so not really a Jenkin side fault. Empty packet is being sent.

I too get the same error :

net.sf.json.JSONException: JSONObject["user"] not found.

Looks like Webhook functionality in Bitbucket was released a bit too early and is quite buggy. It is quite possible that the Jenkin plugin is incompatible, seeing the parsing issue at Jenkin side.
