We are doing Spring 2.7.15 to 3.2.1 Migration.

As part of the code, we have
import org.springframework.mail.javamail.JavaMailSender;
import org.springframework.mail.javamail.MimeMessageHelper;

import jakarta.mail.MessagingException;
import jakarta.mail.internet.MimeMessage;

public class MyEmailService {
private static final Logger logger = LoggerFactory.getLogger(EmailerService.class);

@Autowired
JavaMailSender mailSender;

//As part of the call in a method we are calling
public void sendMyEmail() {
   //This below line throws error
   MimeMessage mimeMessage = this.mailSender.createMimeMessage();
} 

}

We are getting error saying:
java: incompatible types: javax.mail.internet.MimeMessage cannot be converted to jakarta.mail.internet.MimeMessage
