使用SimpleJavaMail时出现的问题：does not match stack map？

Question

之前一直用javax.mail发送Email，但总感觉不太方便，直到发现SimpleJavaMail，是时候放弃自己封装的丑陋的EmailUtil了。

在本地环境（Win10+JDK8）和生产环境（CentOS7+JDK8）都一切正常。

但在部署到阿里的ECS（CentOS8+JDK8）之后，就发现无法发送邮件，错误如下：

java.lang.RuntimeException: java.lang.VerifyError: Instruction type does not match stack map

我的代码：

String server = "smtp.exmail.qq.com";
Integer port = 587;
String userName = "[e-mail]";
String passWord = "....";

Mailer mailer = MailerBuilder
        .withSMTPServer(server, port, userName, passWord)
        .withTransportStrategy(TransportStrategy.SMTP_TLS)
        .clearEmailValidator()
        .buildMailer();

String from = "[e-mail]";
String to = "[e-mail]";
String subject = "标题";
String content = "内容";

Email mail = EmailBuilder.startingBlank()
        .from("mycomp", from)
        .to(to)
        .withSubject(subject)
        .withPlainText(content)
        .withContentTransferEncoding(ContentTransferEncoding.BASE_64)
        .buildEmail();

mailer.sendMail(mail);

头一次遇到这种问题，不知道如何下手解决了。
