GitBox

reta opened a new pull request #683:
URL: https://github.com/apache/cxf/pull/683


   1. Aligning MP Client implementation to use only one executor service, configured through `MicroProfileClientFactoryBean` and propagated via contextual property `EXECUTOR_SERVICE_PROPERTY`
   2. Always initialize executor service in the `MicroProfileClientFactoryBean`, using `ForkJoin` pool as default if not specified
   3. Removed async delegation from `MPRestClientCallback::createFuture` since it is always executed in the context of executor service (configured through `MicroProfileClientFactoryBean`)

Review comment:
       maybe make it lazy to not create it (forkjoin common pool) if the app does not use it and the client for its lifecycle?

Review comment:
       think you can use JsonbJaxrsProvider from johnzon-jsonb instead of importing this one which does not use jsonb, would be more consistent with MP probably?

Review comment:
       Thanks for the review! This one is very tricky to make lazy. Essentially, this `executorService` sets (or unsets) the CXF's `EXECUTOR_SERVICE_PROPERTY` which basically controls the how the async client invocation should be handled (it is used by MP and other clients). If we don't provide `executorService` upfront, the property won't be set and async callback (`MPRestClientCallback`) is going to be called in the context of CXF's work queue pool. The common `ForkJoinPool` is present 99.9% of the time.

Review comment:
       es = new LazyExecutor();
   
   lazyexecutor 100% delegates to common one, it just enables to not create threads until it is done so the pool is async, not the facing instance ;)

Review comment:
       Sorry, this part I didn't get. With respect to threads (aka workers), `ForkJoinPool` is 100% lazy: it does not preallocate threads upfront if there is no work to be done, the `ForkJoinPool`'s threads are created only when work is scheduled.

Review comment:
       Yep, was not a good phrasing choice. Fact is getting triggers the common (var) instantiation which brings a lot of work - for nothing in some cases and that's what I'd like to avoid.
   Having a facade enables to just load a class and do a new without dependencies (static init) and speed up the startup.
   We faced it in openwebbeans and this is why we have that wrapper https://github.com/apache/openwebbeans/blob/9b04c5e906294bcad7c61f30b5c5fcc8956b2f17/webbeans-impl/src/main/java/org/apache/webbeans/event/NotificationManager.java#L954.

       Guess you want to bypass the dopriviledge when there is no security manager
   Otherwise looks good to me now
