Message.getContent() returns IMAPInputStream

Question

When I run my class normally messageContent usually returns a class that is a Multipart. But when I package my appliction into a jar and run it, messageContent is returned as a IMAPInputStream. I do not know how to handle this, and can't find this class in the javadoc - what can I do?
Message message = ...; // left out here
Object messageContent = message.getContent();
System.out.println("class type: " + messageContent.getClass());class type: class com.sun.mail.imap.IMAPInputStream

Hi, thank you. I will try to analize it. It's running under oc4j and jdk 1.6
And I have only this message:
