Folder.copyMessages

Hi !

I am writing some code to move a mail from a folder to another. The idea is
to copy it to another folder and then delete the orignal.

Is that normal that this code:

private void moveMail(Message message){
	try {
		Folder dossierSrc = message.getFolder();
		Store store = dossierSrc.getStore();
		Folder dossierDest = store.getFolder("processedMails");
		if (dossierDest != null && dossierDest.exists()) {
			dossierSrc.copyMessages(new Message[]{message}, dossierDest);
			message.setFlag(Flags.Flag.DELETED,true);
		} 
	} catch (MessagingException e) {
			e.printStackTrace();
	}
}

leads to a NPE:

java.lang.NullPointerException
	at
gnu.mail.providers.imap.IMAPMultipartDataSource.getInputStream(IMAPMultipartDataSource.java:102)
	at javax.activation.DataHandler.writeTo(DataHandler.java:215)
	at javax.mail.internet.MimeMessage.writeTo(MimeMessage.java:1618)
	at gnu.mail.providers.imap.IMAPMessage.writeTo(IMAPMessage.java:859)
	at javax.mail.internet.MimeMessage.writeTo(MimeMessage.java:1553)
	at gnu.mail.providers.imap.IMAPMessage.writeTo(IMAPMessage.java:845)
	at gnu.mail.providers.imap.IMAPFolder.appendMessages(IMAPFolder.java:712)
	at javax.mail.Folder.copyMessages(Folder.java:669)
	at TestDeplacementMailGNU112.moveMail(TestDeplacementMailGNU112.java:63)
	at TestDeplacementMailGNU112.test(TestDeplacementMailGNU112.java:47)
	at TestDeplacementMailGNU112.main(TestDeplacementMailGNU112.java:31)


Whereas that piece of code works fine:

private void moveMail(Message message){
	try {
		Folder dossierSrc = message.getFolder();
		Store store = dossierSrc.getStore();
		Folder dossierDest = store.getFolder("processedMails");
		if (dossierDest != null && dossierDest.exists()) {
			dossierDest.appendMessages(new Message[]{message});
			message.setFlag(Flags.Flag.DELETED,true);
		} 
	} catch (MessagingException e) {
			e.printStackTrace();
	}
}


Is there any known issue in the Folder.copyMessages method? 

I did the test with GNU-mail 1.1.2

Have a nice day!

thanks,
