Run and close child context from parent app

Question

I'm using spring application builder to run child context application (spring Cloud task) from parent. I'm also passing running parent context to the builder of child application - it has DataSource bean defined and I want it to be used by task as well.

My problem is that when the child context is closed, all parent bean are also destroyed. Am I doing something wrong?

How can I share beans from parent context with child and still keep them alive when the child context exits.

@Component
public class ClassInParentContext{

 @Autowired
 private ConfigurableApplicationContext parentAppCtx;

 @Autowired
 private DataSource ds; //this bean is defined in parent context and I want it to be passed to child but not to be disposed when the child context closes.

 public void onSomeEventInParentContext(){
    new SpringApplicationBuilder(com.app.child.Child.class)
            .parent(parentAppCtx)  
            .run(args); //this context is autoclosed by spring cloud task 
 }
}

@EnableTask
public class Child{
}

Thanks

Don't describe your code. Post it. – JB Nizet Jun 16 '18 at 12:06 — JB Nizet, Jun 16 '18 at 12:06

After talking to spring-cloud-task team turns out that the parent context implicitly, forcibly and intentionally closed when task ends.
