> Hi
> Currently Hazelcast component creates its own HZ instance regardless if a
> reference to a HZ instance is provided or not. So in the case of a reference
> of HZ instance is provided, the one created by the component does not get
> shutdown - see below code snippet, doesn't get shutdown. So one end up with
> multipole instances.
> I believe the component should not create its own instance at the doStart()
> method. It should first check if a reference to HZ instance is provided, if
> yes then use it and if not create its own.
> I have made the changes to reflect the correct behaviour described above. The
> changes will make sure only one instance of HZ is created. Also, added the
> ability to reference HZ instance by its name.

> * Update the wiki to show how to reference HZ by its name
> * Update the wiki to show the newly introduced parameter
> (hazelcastInstanceName)
> * Update the wiki to ideally show an example of how to publish HZ instance as
> an OSGI service for reuse by multiple bundles.

> * No longer the component creates its own HZ instance in doStart() method.
> * When the component is initialised, only one instance is either been created
> or use the referenced on in the endpoint.
> * Ability to reference HZ instance by its name. This will serve the use case
> whereby the hazelcast cluster is running remotely or not part of the camel
> context.
