Keith Wall commented on QPID-7409:
----------------------------------
We agreed that we will push the responsibility for the limit to the operation.
The operation will need to be able to get the Accept-Encoding parameter. For
now we will expose the headers to the operation as a thread local.

> When viewing messages through the web management console, if the message is
> of type such as a list or map currently the user sees the bytes of the
> underlying AMQP datastructure. Instead, the preview area should display the
> data in a human friendly way.
> The managed operation {{Queue#getMessageContent}} will be enhanced to be
> capable of returning a message in JSON format if possible with an optional
> parameter {{returnJson}}. If rather than returning the message's content
> bytes directly, it should first convert the message to an {{InternalMessage}}
> (MessageConverterRegistry.getConverter(serverMessage.getClass,
> InternalMessage.class).convert(...)) then use the JSON serialiser to serial
> the MessageBody of the resulting internal message.
> Within the WMC, if the resulting object is of a previewable type (string,
> map, list etc) and the content is not too long, the content should be added
> to a scrollable preview pane of the message dialogue by traversing the object
> tree and producing a human readable representation of its structure and
> content. (Perhaps an approach such as
> https://stackoverflow.com/questions/13341373/render-arbitrary-json-in-html
> will help)
