> Each call to Enum.values() copies the Enum's values into a new array. When
> Enum.values() is called often, this causes extra unnecessary garbage
> collection pressure.
> Find instances where Enum.values() is called a lot and provide an
> improvement. Do not include cases where Enum.values() is called in exception
> handling or during initialization.
> An interesting blog that explains the values() behavior for one use case:
