[jira] [Commented] (CAMEL-18338) IMAP MailConsumer NullPointerException due CAMEL-16180
[ https://issues.apache.org/jira/browse/CAMEL-18338?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=17574535#comment-17574535 ]
Florian Fiby commented on CAMEL-18338:
--------------------------------------
[~davsclaus] issue is related with commit e02cb28f4b797561ce2b7580206ca26037dd86a7.
After disconnect folder is null and polling is done anyway which leads to NullPointerException.
I'm not sure whether the intention was to re-create the connection in this catch or to exit poll and reopen connection with next poll (comment vs logging).
{{ try {}}
{{ if (!folder.isOpen()) {}}
{{ folder.open(Folder.READ_WRITE);}}
{{ }}}
{{ } catch (MessagingException e) {}}
{{ // some kind of connectivity error, so lets re-create connection}}
{{ String msg = "Error opening mail folder due to " + e.getMessage() + ". Will re-create connection on next poll.";}}
{{ LOG.warn(msg);}}
{{ if (LOG.isDebugEnabled()) {}}
{{ LOG.debug(msg, e);}}
{{ }}}
{{ disconnect();}}
{{ }}}
