LUCENE-7077: fail precommit on useless assignment
> fail precommit on useless assignment
> ------------------------------------
>
> Key: LUCENE-7077
> URL: https://issues.apache.org/jira/browse/LUCENE-7077
> Project: Lucene - Core
> Issue Type: Bug
> Reporter: Robert Muir
> Attachments: LUCENE-7077.patch

>
> I found LUCENE-7073 because of a compiler warning in my IDE. It slipped all
> the way through buggy tests too! I think we should fail when "assignment has
> no effect", rather than just rely on someone to catch it visually.
> This is very specific and will not trigger a bunch of false positives: but
> can indicate a common bug in e.g. constructors for POJO classes and so on.
