In the "Extended E-mail Notification" section of the "Configure System" page, "Default Recipients" does not save any values any more. I have tried listing the email addresses with spaces as well as commas as delimiters. After adding them and saving the config, when I go back, the list is empty again. This is further confirmed by my not receiving the email when it is sent. Nothing appears in the jenkins log file when I save the recipients so I haven't a clue why this is happening.
