> For jms messages, the useOriginalMessage does not work when headers are changed during the route because the DefaultUnitOfWork's headers are the same object as the in message's headers.
> In DefaultUnitOfWork, this.originalInMessage.setHeaders(exchange.getIn().getHeaders()); should be changed to create a copy of the headers instead of directly assigning.
> Maybe changed to this.originalInMessage.setHeaders((Map<String,Object>) new CaseInsensitiveMap(exchange.getIn().getHeaders()));
