Uwe Schindler commented on SOLR-17027:
--------------------------------------
Hey, stupid question: why discuss about zero-sized vs. predefined length.
We're on Java 11+, so the modern, typesafe way is this:
{{Collection#toArray(String[]::new)}} or {{Collection#toArray(Foobar[]::new)}}.
And it has best performance as there are no allocations.
