Claus Ibsen resolved CAMEL-22627.
---------------------------------
Resolution: Fixed
> Camel fails graceful shutdown with wiretap/kamelet
> --------------------------------------------------
>
> Key: CAMEL-22627
> URL: https://issues.apache.org/jira/browse/CAMEL-22627
> Project: Camel
> Issue Type: Bug
> Components: camel-core, camel-kamelet
> Affects Versions: 4.15.0
> Reporter: dvine
> Assignee: Claus Ibsen
> Priority: Minor
> Fix For: 4.14.3, 4.17.0
>
> Attachments: camelerror.txt

> We have long running tasks and set a large grace period during termination to
> clear these. What we see is errors like:
> org.apache.camel.component.kamelet.KameletConsumerNotAvailableException: No
> consumers available on endpoint: kamelet://<removed>?<removed>
> The code around this is called from a wiretap:
> .wireTap( kamelet://<removed>?<removed>") like so. If I replace it with .toD
> then we do not see the issue.
> During normal operation the logs show:
> [d #45 - WireTap] o.a.c.i.e.AbstractCamelContext :
> kamelet://<redacted> converted to endpoint: kamelet://<redacted> by
> component: org.apache.camel.component.kamelet.KameletComponent@320aecd3
> [d #45 - WireTap] o.a.c.s.s.BaseService$Holder : Starting
> service: kamelet://<redacted>
> [d #45 - WireTap] o.a.c.s.s.BaseService$Holder : Started service:
> kamelet://<redacted>
> [d #45 - WireTap] o.a.c.s.c.ServicePool : Creating service
> from endpoint: kamelet://<redacted>
> If camel is shutting down then it forgoese any starting service calls:
> [d #46 - WireTap] o.a.c.i.e.AbstractCamelContext :
> kamelet://<redacted> converted to endpoint: kamelet://<redacted> by
> component: org.apache.camel.component.kamelet.KameletComponent@3d1cb317
> [d #46 - WireTap] o.a.c.s.c.ServicePool : Creating service
> from endpoint: kamelet://<redacted>
> And then leads later to the KameletConsumerNotAvailableException.
> Which makes sense because the code around the starting only starts if camel
> is started and running from what I can see. However this means we cannot
> gracefully complete shutdown.
> I entered this as a bug because it seems to be a problem with
> wiretap/kamelets more specifically but advice regarding a work around for
> this would be appreciated. I havent managed to repeat this with non kamelets.
