Sending mail with Google Apps Engine

I'm trying to send an e-mail to the instructions: https://cloud.google.com/appengine/docs/java/mail/sending-mail-with-mail-api

But I get this error:

com.google.apphosting.api.ApiProxy$CancelledException: The API call remote_socket.CreateSocket() was explicitly cancelled.

What could be the reason?

My method:

private void sendMail(String mail) {
        Properties props = new Properties();
        Session session = Session.getDefaultInstance(props, null);

        try {
            Message msg = new MimeMessage(session);
            msg.setFrom(new InternetAddress("[email protected]", "Mr.x"));
            msg.addRecipient(Message.RecipientType.TO,
                    new InternetAddress("[email protected]", "Mr.y"));
            msg.setSubject("Test mail");
            msg.setContent(mail, "text/html; charset=\"UTF-8\"");
            Transport.send(msg);
        } catch (AddressException e) {
            e.printStackTrace();
        } catch (MessagingException e) {
            e.printStackTrace();
        } catch (UnsupportedEncodingException e) {
            e.printStackTrace();
        }
    }

I found a mistake in pom.xml, library javax.mail has been added, but google is using his lib, which is included in the appengine-api-1.0-sdk I deleted javax.mail, add appengine-api-1.0-sdk in Maven, and it worked!
