Dawid Weiss commented on LUCENE-7796:
-------------------------------------
Sorry, I wasn't clear -- this method would *still* unconditionally always throw
an exception. So even if you forgot to do a {{throw}}, the code wouldn't get
past this method. The return unchecked exception is only useful for cases like
switch statements or (theoretically) reachable code but practically we know
reThrow never returns. See Mike's code in LUCENE-7792 and you'll see what I
mean.
> Make reThrow idiom return Throwable to enforce code unreachability

> A spinoff from LUCENE-7792: reThrow can return an unchecked exception so that
> one can use {{throw reThrow(...)}} idiom to let the compiler know subsequent
> code would be unreachable.
