--------------------------------------

Indeed the new implementation should address this.

> Say I have a {{@Timeout}} method in my application, which uses a {{@RequestScoped}} service:
> {code:java}
> @Inject
> private MyService service;
> @Timeout
> public String doSomething() throws InterruptedException {
>     return "Hello " + service.call();
> }
> {code}
> The method isn't {{@Asynchronous}}, so it's supposed to be executed on the caller thread and hence the CDI contexts should be available. However, they are not:
> {code}

> {code}
> Clearly the {{@Timeout}} methods are always executed on a separate thread (see {{HystrixCommandInterceptor.initSetter}}):
> {code:java}
> // Async and timeout operations use THREAD isolation strategy
> if (operation.isAsync() || operation.hasTimeout()) {
>     propertiesSetter.withExecutionIsolationStrategy(HystrixCommandProperties.ExecutionIsolationStrategy.THREAD);
> } else {
>     propertiesSetter.withExecutionIsolationStrategy(HystrixCommandProperties.ExecutionIsolationStrategy.SEMAPHORE);
> }
> {code}
