Error handling

When a scheduled method throws an exception it will be handed to the default ExceptionHandler. The default implemenation simply logs the stack trace with some additional information about the scheduled method.

You can specify a custom ExceptionHanlder on a scheduled method using @OnError:

@Scheduled
@SimpleTrigger(5000)
@OnError(MyCustomExceptionHandler.class)
public void scheduledMethod() {

}

Please note that the exception handler is eagerly instantiated by the framework before scheduling the method the first time. Thus you can't inject ScheduledScope or ExecutionScope types into your handler. However, the handler's onException method will be called while the ScheduledContext is still active. This means you can inject a Provider or a scoped proxy of your class and access it within onException.
