"Access to default session denied" when sending email with gmail

Question

I think I may have overloaded my uses with my account, because the code used to work just fine (and I tested it quite often--my program sends an HTML email containing my todo list, and I was working on the layout).
I'm hoping it's the code, though, so I'm posting it here to see if there is anything wrong with it (that would cause the "Access to default session denied" SecurityException:
protected static void sendMsg(String contents) throws Exception {
         Security.addProvider(new com.sun.net.ssl.internal.ssl.Provider());
                          Properties props=new Properties();
                          props.setProperty("mail.transport.protocol","smtp");
                          props.setProperty("mail.host","smtp.gmail.com");
                          props.put("mail.smtp.auth","true");
                          props.put("mail.smtp.port","993");
                          props.put("mail.debug","true");
                          props.put("mail.smtp.socketFactory.port","993");
                          props.put("mail.smtp.socketFactory.class","javax.net.ssl.SSLSocketFactory");
                          props.put("mail.smtp.socketFactory.fallback","false");
                          Session session=Session.getDefaultInstance(props,new GJMailAuthenticator());
        Transport transport = session.getTransport();
        MimeMessage message = new MimeMessage(session);
        message.setSubject("Testing javamail html");
        message.setContent
           (contents, "text/html; charset=ISO-8859-1");
        message.addRecipient(Message.RecipientType.TO,
           new InternetAddress("[email protected]"));
        transport.connect();
        transport.sendMessage(message,
           message.getRecipients(Message.RecipientType.TO));
        transport.close();
class GJMailAuthenticator extends javax.mail.Authenticator{
              protected PasswordAuthentication getPasswordAuthentication()
                  return new PasswordAuthentication("[email protected]","asdfasdf");
     }any idea what went wrong?

Replace Session.getDefaultInstance with Session.getInstance.
