> @RequestScoped isn't honoured (don't see new instance each request)
> The services are:
> * AcceptHeadersService
> * CommandContext
> * InteractionContext
> * Scratchpad
> * PublisherDispatchServiceDefault
> That's a big problem... I would expect them to be instantiated (and call
> @PostConstruct/@PreDestroy) for each request. As it is, they seem to be
> singletons.
> Also, these three further domain services are annotated with @RequestScoped,
> but also implement WithTransactionScope:
> * ChangedObjectService
> * QueryResultsCacheDefault
> * MetricsServiceDefault
> This callback is being called, so they are not memory leaking over time, but
> they are not thread-safe for concurrent transactions. At any rate, we should
> get rid of this home-grown transaction stuff and instead use Spring's
> @TransactionScope
> ~~~
> Also, AcceptHeadersServiceForRest (the RO implementation) although it is
> annotated with @RequestScoped, seems to have its own thread-local. This
> could probably be removed if it can be made to be properly request-scoped.
