Can a sub task be in Resolved status even when the sprint has been closed

[Yugank Bhatnagar]

Hi

I encountered a problem. I searched for issues using JQL 

project = XXX AND Sprint in closedSprints()

It gave me the list of issues including stories and sub tasks. But to my surprise I found a sub task whose parent story was closed. I am wondering how it is possible?

Can someone help here 

Thanks

The JQL query is going to return all issues in project XXX that were also in any sprint that is now closed.   However a sprint in JIRA can be closed without completing all the issues in the sprint.   Also an issue could have been in multiple sprints.

So I'm not sure if ths information helps.  Could you let me know why finding a parent in the closed status is surprising here?  I guess I don't fully understand the confusion here.
