> Boot server, connect CLI and reload.
> As an example, the PathAddress [("core-service" => "management"),("management-interface" => "http-interface")] is leaked after the first reload (and only the first one, additional reloads don't create leak).
> Attached heapdump, server.log and configuration used (reduced standalone.xml).
> server.log contains traces of Instrumented PathAddress. Each created instance has an ID to track finalization.
> server.log contains stacktrace of PathAddress allocation.
> You will notice:
> 0) Server starts and allocates 9 PathAddress for the management-interface=http-interface.
> 1) GC occurs (forced from remote), 7 PathAddress are finalized. Instance 149 and 338 are not finalized.
> 2) Reload occurs and allocates 9 new PathAddress for the management-interface=http-interface.
> 3) GC occurs (forced from remote), 8 PathAddress are finalized. Instance 338 is Finalized but NOT instance 149.
> 4) We have 3 remaining PathAddress 149, 600 and 789
> 5) Reload occurs and allocates 9 new PathAddress for the management-interface=http-interface.
> 6) GC occurs (forced from remote), 9 PathAddress are finalized, we still have 149, new ones being 1029 and 1218.
> So we have a leak of 1 PathAddress instance, instance 149.
