MP fault tolerance: CDI contexts not available in @Timeout methods

    XMLWordPrintable

Details

    Description

      Say I have a @Timeout method in my application, which uses a @RequestScoped service:

      @Inject
private MyService service;

@Timeout
public String doSomething() throws InterruptedException {
    return "Hello " + service.call();
}

      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:

      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

      Clearly the @Timeout methods are always executed on a separate thread (see HystrixCommandInterceptor.initSetter):

      // Async and timeout operations use THREAD isolation strategy
if (operation.isAsync() || operation.hasTimeout()) {
    propertiesSetter.withExecutionIsolationStrategy(HystrixCommandProperties.ExecutionIsolationStrategy.THREAD);
} else {
    propertiesSetter.withExecutionIsolationStrategy(HystrixCommandProperties.ExecutionIsolationStrategy.SEMAPHORE);
}
