Today, or yesterday, mail sent through a call made from a facesrequest under testng stops producing html-content. The mail is rendered and sent, but all the html-tags are missing. The text is indented as if the tags were in place, but the tags themselfes are gone. All mails works as they should within a normal application flow. There was some modifications made to the mocking framework during the past days, might this have some correlation? Seam trunk used.
