I'm trying to write a MIME message to the console.

ByteArrayOutputStream out = new ByteArrayOutputStream();
MimeMultipart replyMsg = mdnCreator.createMDNData();
System.out.println(new String(out.toByteArray()));

I'm using bouncycastle too in this code. If I use bouncycastle 1.65, it works well. If I use bouncycastle 1.66 or newer, I get this:

Exception in thread "main" javax.activation.UnsupportedDataTypeException: no object DCH for MIME type multipart/report; report-type=disposition-notification; 
at javax.activation.ObjectDataContentHandler.writeTo(
at javax.activation.DataHandler.writeTo(
at javax.mail.internet.MimeBodyPart.writeTo(
at javax.mail.internet.MimeBodyPart.writeTo(
at javax.mail.internet.MimeMultipart.writeTo(

Do you have any idea why this is happening?
