I think this is nicer: ``` List.of() List.of("a") List.of(1,2,3) ``` than ``` Collections.emptyList() List.of("a") List.of(1,2,3) ``` The performance improvements of bimorphic vs polimorphic calls in this case will likely not be measurable in this case. However, as using `List.of` everywhere arguably makes the code more consistent and simpler, any minor gains are just a welcome extra. -- This is an automated message from the Apache Git Service.
