> Audit usage of ExecutorService#submit in Solr codebase
> ------------------------------------------------------
>
> Key: SOLR-17448
> URL: https://issues.apache.org/jira/browse/SOLR-17448
> Project: Solr
> Issue Type: Improvement
> Affects Versions: 9.7
> Reporter: Andrey Bozhko
> Priority: Minor
> Labels: pull-request-available
> Fix For: 9.8
>
> Time Spent: 2.5h
> Remaining Estimate: 0h
>
> There are quite a few places in Solr codebase where the background task is
> created by invoking `ExecutorService#submit(...)` method - but where the
> reference to the returned future is not retained.
> So if the background task fails for any reason, and the task doesn't itself
> have a try-catch block to log the failure, - the failure will go completely
> unnoticed.
>
> This ticket is to review the usage of ExecutorService#submit method in the
> codebase, and replace those with Executor#execute where appropriate.
