Hello,

since v8.6.0 I get the following stacktrace when attempting to send out a mail (up to current v8.12.2). v8.5.1 is working without any issues for me. Maybe I need to configure something differently since v8.6.0 and I'm just overseeing the information somewhere? Would really appreciate If you could help me figure it out.

I'm using jdk 21.0.5

simplified code:

MailerBuilder mailer = MailerBuilder
                .withSMTPServer("<host.ip.address>", 25)
                .async()
                .buildMailer();

EmailPopulatingBuilder emailBuilder = EmailBuilder.startingBlank()
                .to("<recipient.mail.address>")
                .from("<from.mail.address>")
                .withSubject("<subject>")
                .withHTMLText("<html body>");

mailer.sendMail(emailBuilder.buildEmail());

Stacktrace:
