How can I interrupt IMAP's IDLE?

Question

I am using the Javamail API connecting to my IMAP server. Everything is working great with the javax.mail.Folder.idle() method. My listener gets called when a new mail comes

A proper way to abort IDLE command is the following snippet. Note that the Folder instance should be the same as the one used to start idling. I've tested the other solutions proposed on this thread but they didn't work in my case.

IMAPFolder folder = store.getFolder("INBOX");
try {
  folder.doOptionalCommand("Abort IDLE error mesage", new IMAPFolder.ProtocolCommand() {
  @Override
  public Object doCommand(IMAPProtocol p) throws ProtocolException {
    p.idleAbort();
    return Boolean.TRUE;
  }
});
} catch (MessagingException e) {
  e.printStackTrace();
}
