Lars Storm (Systematic) updated CAMEL-20806:
--------------------------------------------
Affects Version/s: (was: 2.25.0)
> ProducerCache may reference producers from stopped endpoints
> ------------------------------------------------------------
>
> Key: CAMEL-20806
> URL: https://issues.apache.org/jira/browse/CAMEL-20806
> Project: Camel
> Issue Type: Bug
> Components: camel-core
> Affects Versions: 4.4.1
> Reporter: Lars Storm (Systematic)
> Priority: Minor
>
> *Problem in short:*
> The DefaultProducerCache created from .toD(...) in a route may reference
> producers created from endpoints that have been stopped.
> Specifically the endpoint may have been stopped from
> camelContext.removeEndpoint(...)
> *Proposal:*
> ProducerCaches should be notified when an endpoint is stopped. The
> ProducerCache may then find and evict the leaked producer.
> *Use case:*
> In some cases we create a n endpoint (e.g. CxfEndpoint) programmatically per
> tenant (Multi-tenant setup) and store the endpoint in a non-Camel cache. The
> endpoint is then passed on to a Camel route on request.
> The endpoint is then dynamically used in a .toD(...)
> However the local cache may decide to stop the endpoint due to changes
> performed in tenant properties and create a new one. e.g. changing the
> endpoint url or similar.
> In that case the TenantEndpointCache removes the current endpoint the camel
> context and creates a new one which is added to the context.
> Example route code:
> {noformat}
> .setProperty("endpoint").method(TenantEndpointCache.class, "createEndpoint")
> .toD("${exchangeProperty.endpoint}"){noformat}
