[jira] [Commented] (CAMEL-17374) RecepientList doesnt stop after CamelContext.shutdown()

["Stepan Shcherbakov (Jira)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/CAMEL-17374?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=17501732#comment-17501732 ] 

Stepan Shcherbakov commented on CAMEL-17374:
--------------------------------------------

Sorry, forgot about this bug. But today it appeared again :(

I use camel with version 3.7.2.

In our application there are a lot of camel contexts and we use a *controller* to control them. That is why JVM is still running after context shutdown.

*Controller* creates new camel context every start and does not reuse it after shutdown.

> My program has camel route:
> timer -> direct:send:to:recipientList
> direct:send:to:recipientList -> recipientList -> direct1
>                                                                     -> direct2
> direct1 -> processor -> file
> direct2 -> processor -> http (which fails with error)
> *redelivery set to infinite (-1) and redelivery delay set to 100ms*
> I called CamelContext.shutdown() and it shutdowned successful.
> Suddenly, after 30s from shutdown was completed, 3 recipientList processors raised and started to redelivery:
> 2021/12/23-13:40:35.265 [Camel (ContextName) thread #10 - RecipientList](463) W! org.apache.camel.processor.errorhandler.RedeliveryErrorHandler - Error during processing OnExceptionOccurred. This exception is ignored.
> java.lang.IllegalArgumentException: my exception

> Exception from error handler is ok because I throw it when camel context is stopped.
> *Why there are working camel threads after context was shutdowned?*
> These threads never stop and trying to redelivery every 100ms (as redelivery delay set).
