some questions in Asynchronous

[caiyunCheng]

I have a time-consuming operation，so I use Java1.8 asynchronous.  Like this :

function getSomeThing(){

    CompletableFuture<List<String>> list = CompletableFuture.supplyAsync(() ->{

         getList();    //task some seconds;  

    });

}

function getList(){

    ApplicationUser loggedUser = JiraAuthenticationContext.getLoggedInUser();

}

My question is that the above loggerUser will be null,  but I can get it if I don't user CompletableFuture,  I don't know why ?? 

If someone can help  ,  thank you so much !!!

Hello @caiyunCheng ,

Please notice that this might not be the best place to get help on development related questions. So, in case of no reply, I'd advise to refer to the resources listed in https://developer.atlassian.com/resources. 

Specifically:

• Ask the Developers Community
• Create a Developer Support Request
