Michael McCandless commented on LUCENE-7470:
--------------------------------------------
I think we can just poach the code from the {{tools/}} directory.
But probably we would need a new annotation {{SuppressExceptionHandlingChecks}}
or some such for code that is doing tricky exception handling?

> Project: Lucene - Core
> Issue Type: Bug
> Reporter: Michael McCandless
>
> [~rcmuir] created a nice tool to look at the Java bytecode to determine
> whether e.g. a {{finally}} or {{catch}} clause may ignore the original root
> cause exception, here:
> https://github.com/rmuir/elasticsearch/tree/catchAnalyzer
> It's a fork of ES but I think maybe we can extract it and use it in Lucene.
> Unlike Python, Java unfortunately does not seem to have safeguards against
> exceptionally handling code accidentally losing the original exception.
