Not a real answer, but I got around this by using Mailkit's IMAP. Also, this is C#, not Java code, but maybe it can help people running into the same problem:

      var emails = new List();

      using (var client = new ImapClient())
      {
        client.Connect("imap.gmail.com", _smtpConfig.SSLIMAPPort, SecureSocketOptions.SslOnConnect);
        client.ServerCertificateValidationCallback = (s, c, h, e) => true;
        client.SslProtocols = System.Security.Authentication.SslProtocols.Tls12;
        client.AuthenticationMechanisms.Remove("XOAUTH2");
        client.Authenticate(smtpConfig.PopUsername, smtpConfig.PopPassword);

        client.Inbox.Open(FolderAccess.ReadWrite);
        var items = client.Inbox.Fetch(0, -1, MessageSummaryItems.UniqueId | MessageSummaryItems.BodyStructure);

        foreach (var item in items)
        {
          if (item.TextBody != null)
          {
            var mime = (TextPart)client.Inbox.GetBodyPart(item.UniqueId, item.TextBody);
            var text = mime.Text;

            var email = new EmailMessage
            {
              Body = text
            };

            emails.Add(email);
          }
        }

        client.Disconnect(true);
      }

      return emails;
