ARIES-2120 Change DistributionProvider to return a Closeable ImportedService so
that resources can be properly released
> Imported service proxy cannot be properly closed (potential leak)
> -----------------------------------------------------------------
>
> Key: ARIES-2120
> URL: https://issues.apache.org/jira/browse/ARIES-2120
> Project: Aries
> Issue Type: Bug
> Components: Remote Service Admin
> Affects Versions: rsa-1.16.1
> Reporter: Amichai Rothman
> Priority: Major
> Fix For: rsa-2.0.0
>
>
> The main DistributionProvider interface contains two methods,
> exportService and importEndpoint. The former returns an Endpoint which is an
> inteface that extends Closeable, and thus can later be closed by RSA as
> necessary. However, importEndpoint returns the actual proxy instance itself -
> it is created and returned and passed transparently to the caller.
>
> The proxy implementation would likely require opening some reasources like
> network sockets etc. in order to do the remote invocation, however in the
> current design there is no lifecycle management, specifically no way to
> properly close the proxy and its backing resources.
>
> Having the returned proxy itself implement Closeable would be problematic,
> since the exported/imported interface may have its own close() method
> (invoked remotely) which we do not want to hide. Perhaps, like with the
> exports, the returned object should not be the proxy itself but a wrapper
> class that contains the proxy but is also Closeable or contains some other
> form of lifecycle management, so it can be called by RSA when the proxy and
> its resources should be disposed of. Perhaps there are other, better ways of
> doing this, but they DistributionProvider interface may have to change in any
> case.
