I have a use case where I want to use Long.hashCode(long value).
When I'm invoking it with Long that is actually null, I'm receiving NullPointerException.
NullAway does not provide any warning that the unboxing may produce NullPointerException.

Exception in thread "main" java.lang.NullPointerException: Cannot invoke "java.lang.Long.longValue()" because "a.longValue" is null

Reproducible example is available here https://github.com/violetagg/nullaway-unboxing, you need to run the org.example.Main#main
