[Classpathx-javamail] Bug in 1.1.2: Folder.search() alters Folder.mode (works with 1.1.1)

[Boris Folgmann]

Hi,

I've got a code that worked perfectly with mail 1.1.1 but has problems with 
1.1.2.

----------------------------------------------------------------
store.connect();
Folder folder = store.getFolder("a cyrus imap folder");
folder.open(Folder.READ_WRITE);
log.info("Total messages: " + folder.getMessageCount());

Message[] msgs = folder.search(aTerm);
processMessages(msgs);
folder.expunge();
// folder.getMode() still returns Folder.READ_WRITE here

msgs = folder.search(aDifferentTerm);
// folder.getMode() now returns Folder.READ_ONLY!!
processMessages(msgs);
folder.expunge();

----------------------------------------------------------------

The second folder.expunge() throws

javax.mail.MessagingException: Folder was opened read-only
        at gnu.mail.providers.imap.IMAPFolder.expunge(IMAPFolder.java:530)

Using some more log.info() I found out that the Folder.mode is altered by 
the second search. I couldn't find anything in the JavaDocs that this is a 
regular behaviour. As it worked with the previous release, you may know 
what the problem could be.

I also update jaf from 1.0 to 1.1.1

cu,
