-------------------------------------
I have attached a patch to this issue.
> Thread leak for camel-mina2 consumers
> -------------------------------------
>
> Key: CAMEL-9738
> URL: https://issues.apache.org/jira/browse/CAMEL-9738
> Project: Camel
> Issue Type: Bug
> Components: camel-mina2
> Affects Versions: 2.16.2
> Reporter: Thomas Papke
> Attachments: ConsumerDispose.patch
>
>
> The camel-mina2 consumer
> ({{org.apache.camel.component.mina2.Mina2Consumer.doStart()}}) internally
> start a Mina2 IoAcceptor ({{org.apache.mina.core.service.IoAcceptor}}), but
> the {{org.apache.camel.component.mina2.Mina2Consumer.doStop()}} do not invoke
> {{acceptor.dispose(true);}} to release the threadpool started by Mina2.
> *Current behavior:* While stopping the web application, the threadpool
> started by Mina2 IoAcceptor will not be stopped, so we have several thread
> which do not properly shutdown.
> *Current workaround:* I create custom CamelShutdownStrategy and collect all
> Mina2Consumer and invoke Mina2consumer.getAcceptor.dispose(true); OR as an
> alternative create a dedicated consumer and overwrite the stop method of the
> Mina2 consumer as seen here:
> https://github.com/oehf/ipf/commit/12fdde8df7ebbbb7cd9966aadeab3ea3bed8fe75
> *Suggested bugfix:* In
> {{org.apache.camel.component.mina2.Mina2Consumer.doShutdown()}} call the
> IoAcceptor dispose(true) method after unbind from the address.
