IFS message no longer working in version 1.1.9

Question

The following code worked correctly with version 1.1. I am wondering if the API has changed for the ifsMessage class. If so, where can I find the javadocs for the newer API?
public void sendMail(String subject) {
try {
allocateConnection();
ifsSession.setAdministrationMode(true);
IfsMessage msg = new IfsMessage(ifsSession);
msg.setToHeader(new String[] {SSU_NOTIFY_EMAIL});
msg.setFromHeader(SSU_FROM_EMAIL);
msg.setSubject(subject);
msg.setContentType("text/plain");
msg.send();
releaseConnection();
catch(Exception e){
System.out.println("Error in mail message = " + e);
}// end sendMail
Thanks,
Tony

Answer 1

There are no error messages. If I take out the call to this method everything works fine. When I leave in the call to this method I get a blank screen and no mail sent. Just before the version change the mail worked with the exact same code.
