See JIRA issue here + patch: http://jira.jboss.org/jira/browse/JBMAIL-247 Essentially, I moved the creation of the String array into the try/catch block. If an exception is thrown (i.e., no "content-type" header) then it is eaten and ignored. Note: I kept the "split" around the newline since stored messages have a newline after the "content-type" label. I guess this is one argument in favor of not merging MessageData and Mail classes (i.e., backing a MessageData class with a Mail object per my previous suggestion below) because this function behaves differently in each class. | String[] header = getHeader("Content-Type").split("\\r\\n"); View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=3966092#...
