-----------------------------------

             Summary: 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


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.doStop()}} call the IoAcceptor dispose(true) method after unbind from the address.
