                 Key: GERONIMO-6347

             Project: Geronimo
          Issue Type: Bug
      Security Level: public (Regular issues)
          Components: mail
         Environment: * org.apache.geronimo.javamail:geronimo-javamail_1.4_mail:1.8.3 (I can't

		    log.debug("Getting the {}", target);
		    
		    if (target.equals("inbox")) {
		    	folder = store.getFolder("INBOX");
			} else if (target.equals("sent")){
				folder = store.getFolder("Sent");
			}
		    
		    
		    folder.open(Folder.READ_WRITE);
	
		    // FetchProfile fetchProfile = new FetchProfile();
		    // fetchProfile.add(FetchProfile.Item.CONTENT_INFO);
	
		    messages = folder.getMessages();
		    log.debug("No of messages is {}", folder.getMessageCount());
		    log.debug("No of unread messages is {}",
			    folder.getUnreadMessageCount());

new Object[]{i, date, sender, subject, ""});

				if (messageContentObject instanceof Multipart) {
					log.debug("Found email-{} with attachment", i);

						part = multipart.getBodyPart(j);
						
						contentType = part.getContentType();
						log.debug("Content type is {}", contentType);
						
						if (contentType.startsWith("text/plain")) {
							log.debug("Reading content type text/plain mail");
						} else {
							String fileName = part.getFileName();
							log.debug("File name is {}", fileName);
						}
					}
				} else {		
					log.debug("Found mail without attachment");
					senderStr = ((InternetAddress) message.getFrom()[0]).getPersonal();
					
					if (senderStr == null) {
						senderStr = ((InternetAddress) message.getFrom()[0]).getAddress();
						log.debug("Sender is null, address is {}", sender);
					}
					
					subject = message.getSubject();
					log.debug("subject is {} for message-{} type: {}", new Object[] {

				}
			}
		    folder.close(true);
		    store.close();
		} catch (Exception e) {
			    e.printStackTrace();

Probably relevant code snippet at com.sun.mail.imap.protocol.BODYSTRUCTURE:

    private ParameterList parseParameters(Response r)
			throws ParsingException {
	r.skipSpaces();

	ParameterList list = null;
	byte b = r.readByte();
	if (b == '(') {
	    list = new ParameterList();
	    do {
		String name = r.readString();
		if (parseDebug)
		    System.out.println("DEBUG IMAP: parameter name " + name);
		if (name == null)
		    throw new ParsingException(
			"BODYSTRUCTURE parse error: " +
			type + "/" + subtype + ": " +
			"null name in parameter list");
		String value = r.readString();
		if (parseDebug)
		    System.out.println("DEBUG IMAP: parameter value " + value);
		list.set(name, value);
	    } while (r.readByte() != ')');
	    list.set(null, "DONE");	// XXX - hack
	} else if (b == 'N' || b == 'n') {
	    if (parseDebug)
		System.out.println("DEBUG IMAP: parameter list NIL");
	    r.skip(2);
	} else
	    throw new ParsingException("Parameter list parse error");

	return list;
    }

and the one in javax.mail.internet.ParameterList :

    public void set(String name, String value) {
        name = name.toLowerCase();
        _parameters.put(name, new ParameterValue(name, value));
    }

Workaround:

Replacing geronimo-javamail_1.4_mail with javax.mail:mail:1.4.5 works beautifully. Complete
