javax.net.ssl.SSLHandshakeException: No appropriate protocol (protocol is disabled or cipher suites are inappropriate

Question

I know there is several issue created about this error but nothing was helpful for me. I have method which is sending email with attachment on gmail server and it works fine. yesterday I bought a new mac mini m1. I tried this method to send email but it's throwing this error

 public static void sentEmail(String report){  
    BaseTest base = new BaseTest();
    
      
      String to = base.getProps().getProperty("emailTO"); ;//change accordingly  
      final String user = base.getProps().getProperty("emailFROM");//change accordingly  
      final String password = base.getProps().getProperty("emailPassword");//change accordingly  
       
      //1) get the session object     
      Properties properties = System.getProperties();  
      properties.setProperty("mail.smtp.host", "smtp.gmail.com");  
      properties.put("mail.smtp.auth", "true"); 
      properties.put("mail.smtp.port", "587");  
      properties.put("mail.smtp.starttls.enable", "true");
      
      
      Session session = Session.getDefaultInstance(properties,  
       new javax.mail.Authenticator() {  
       protected PasswordAuthentication getPasswordAuthentication() {  
       return new PasswordAuthentication(user,password);  
       }  
      });  
         
      //2) compose message     
      try{  
        MimeMessage message = new MimeMessage(session);  
        message.setFrom(new InternetAddress(user));  
        message.addRecipient(Message.RecipientType.TO,new InternetAddress(to));  
        message.setSubject("From Mobile Automation Project ");  
          
        //3) create MimeBodyPart object and set your message text     
        BodyPart messageBodyPart1 = new MimeBodyPart();  
        messageBodyPart1.setText("Report");  
          
        //4) create new MimeBodyPart object and set DataHandler object to this object      
        MimeBodyPart messageBodyPart2 = new MimeBodyPart();  
      
        String filename = report;//change accordingly  
        DataSource source = new FileDataSource(filename);  
        messageBodyPart2.setDataHandler(new DataHandler(source));  
        messageBodyPart2.setFileName(filename);  
         
         
        //5) create Multipart object and add MimeBodyPart objects to this object      
        Multipart multipart = new MimeMultipart();  
        multipart.addBodyPart(messageBodyPart1);  
        multipart.addBodyPart(messageBodyPart2);  
      
        //6) set the multiplart object to the message object  
        message.setContent(multipart );  
         
        //7) send message  
        Transport.send(message);  
       
       System.out.println("Report has been sent to: "+ to);  
       }catch (MessagingException ex) {ex.printStackTrace();}  
}

I changed this parameter

properties.setProperty("mail.smtp.host", "smtp.gmail.com");

To this

properties.setProperty("mail.smtp.ssl.trust", "smtp.gmail.com");

But then I'm getting this exception

I had a similar issue and it seems to be related to Deepak's response. Following these instructions solved the problem.

It seems to be necessary to explicitly set required flag and the protocols:

Adding the following settings worked for me:

properties.put("mail.smtp.starttls.required", "true");
properties.put("mail.smtp.ssl.protocols", "TLSv1.2");

I have to add that I tested this on port 465 and the full configuration looks like this

properies.put("mail.smtp.host", "smtp.gmail.com");
properies.put("mail.smtp.port", "465");
properies.put("mail.smtp.auth", "true");
properies.put("mail.smtp.starttls.enable", "true");
properies.put("mail.smtp.starttls.required", "true");
properies.put("mail.smtp.ssl.protocols", "TLSv1.2");
properies.put("mail.smtp.socketFactory.class", "javax.net.ssl.SSLSocketFactory");

Warning do this own risk of enabling tlsv1 and tlsv1.1:

find the directory where java.security file saved. in the case of ubuntu:

/usr/lib/jvm/java-8-openjdk-amd64/jre/lib/security
find jdk.tls.disabledAlgorithms
remove TLSv1, TLSv1.1
reboot the server and run the project to try to send mail again.

To solve that issue, just upgrade the java library used to sendmail. It worked for me.

I faced this issue due to older version of mysql-connector-java-5.1.40-bin.jar Upgrading to 5.1.49 version solved my issue
