Accessing application/json message body of POST request

Hi all,

has someone ever accessed the message body of a post request to cocoon 
which uses application/json as its content type?

The same request is being handled without issues if posted as 
application/x-www-form-urlencoded.

Though, as soon as the content type is changed to JSON, Cocoon appears 
to skip parsing the message body.

Unfortunately it's not me making these POST calls; which is why just 
"switching it" is not an option.

Is there some setting which can tell cocoon to simply continue parsing, 
either regardless of a post's content type (which, of course might raise 
security issues…) or explicitly for application/json ?

Any suggestions are welcome.

Regards,

Bardo
