It is proposed to support transformation of all in-going messages with 'transformation' header, even send with 'content-length' header set. Out-going messages may continue to be sent with 'content-length' header not set, if there are considerations for compatibility.

> The stomp frame translator, such as "transformation:jms-map-json" is ignored if the content-length header is set, so you end up with an ActiveMQByesMessage instead of a ActiveMQMapMessage. The spec says this header is optional, but recommended, so I'm not sure why it's presence or absence is used to determine whether to try the frame translators.
> The code in question is in org.apache.activemq.transport.stomp.JmsFrameTranslator.convertFrame which says:
> {code}
> if (headers.containsKey(Headers.CONTENT_LENGTH) || transformation.equals(Transformations.JMS_BYTE.toString())) {
>   msg = super.convertFrame(converter, command);
> } else {
>  // apply frame translator
> }
> {code}
