> Prevent Reregistration of ScriptEngineManager on ScriptEngineFactory update

>
> The ScriptEngineManager must be recreated when an existing
> ScriptEngineFactory is removed or updated. This causes the
> ScriptEngineManager service to be unregistered and registered again.
> We should probably prevent this, maybe along these lines:
> * Register the ScriptEngineManager as a service during the whole lifetime
> of the Scripting Core
> * The registered ScriptEngineManager is a proxy to the actual
> ScriptEngineManager which gets ScriptEngineFactory registered
> * On ScriptEngineFactory update, the proxied ScriptEngineManager is just
> replaced
