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.
