Hello Andrey, I have a different opinion about this. I think removing existing
calls to `Objects.requireNonNull()` in favour of implicit null check (some
times too far away in the code) isn't useful.
You noted that the implicit `NullPointerException` stacktrace are more user
friendly now. I think you can get similar level of useful information from
`Objects.requireNonNull()` too. In these two specific cases, what you could
perhaps do is change those calls to even pass the `message` so that it's clear
what parameter is `null`. Something like:
Objects.requireNonNull(delimiter, "delimiter");
Objects.requireNonNull(elements, "elements");
