MP fault tolerance: CDI contexts not available in @Timeout methods ------------------------------------------------------------------ Key: WFLY-12982 URL: https://issues.redhat.com/browse/WFLY-12982 Project: WildFly Issue Type: Bug Components: MP Fault Tolerance Affects Versions: 19.0.0.Beta1 Reporter: Miroslav Novak Assignee: Radoslav Husar Priority: Major 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} 2018-04-03 21:16:35,976 ERROR [io.undertow.request] (default task-1) UT005023: Exception handling request to /: org.jboss.weld.context.ContextNotActiveException: WELD-001303: No active contexts for scope type javax.enterprise.context.RequestScoped {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}
