----------------------------------------

[~jarcec] The reason why having a wrapper class is one way to solve  is to exactly do the
same thing, that is make sure we read and parse once,

> The situation of dealing with the post data is very tricky IMHO. 
> 1. {{getRequest().getReader()}} must be called at the first place. As reading position
cannot be reset, you might get unexpected result without notice. SQOOP-1784 is a case of the
situation.
> 2. Sqoop client sends post data as a JSON object rather than query string format. Usually
it'd suggest to wrap the JSON object as value, and key can be named as "jsonObject". The server
will call {{ctx.getParameterValue("jsonObject")}} to get the value.
> I'd suggest to have a {{getRawPostData()}}, so that callers can put finger away from
{{getReader()}}.
