> Key: CAMEL-7739
> URL: https://issues.apache.org/jira/browse/CAMEL-7739
> Project: Camel
> Issue Type: Bug
> Components: camel-core, camel-mail
> Affects Versions: 2.13.0
> Reporter: Laabidi Raissi
> Priority: Minor
> Labels: bug, onCompletion, pop3
> Fix For: 2.13.4, 2.14.2, 2.15.0

>
> I think I found a bug in Camel OncompletionProcessor code when used with a
> Mail poller route and onCompletion.
> The error occurs when the Log level is set to DEBUG or TRACE. In that case
> the logger tries to call the toString() method of the DefaultExchange class
> which calls org.apache.camel.component.mail.MailMessage.toString().
> At that stage, the POP3Folder is already closed.
> A very obvious (but not elegant) solution, would be to add a try-catch block
> to the log instruction.
> Otherwise, I think a good solution is to change the DefaultExchange#toString
> method.
> Here is the exception that occured:
> java.lang.IllegalStateException: Folder is not Open
