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

ByteArrayOutputStream out = new ByteArrayOutputStream();
MimeMultipart replyMsg = mdnCreator.createMDNData();
replyMsg.writeTo(out);
out.close();
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; 
boundary="----=_Part_0_1748430839.1643723297884"
at javax.activation.ObjectDataContentHandler.writeTo(DataHandler.java:909)

at javax.mail.internet.MimeBodyPart.writeTo(MimeBodyPart.java:996)
at javax.mail.internet.MimeMultipart.writeTo(MimeMultipart.java:561)

Do you have any idea why this is happening?

N.B. I'm running my code in an OSGI environment.

I don't get it, `java.mail` doesn't use Bouncy Castle (BC). Perhaps the `mdnCreator.createMDNData()` ... (3 comments)

I understand why Q received some downvotes. You didn't provide enough information to replicate what you've described in the Q. I'm certain that if you add additional information (see another comments for detaisl) downvotes would be removed.
