Affects PMD Version:

Rule:
Please provide the rule name and a link to the rule documentation:
FinalFieldCouldBeStatic
Description:
Suggesting that final fields of array type should be static is generally wrong, unless we also check that there are no mutations.
This is correctly ensured for final double coordinates = new double[]{0, 0} but not final double coordinates = {0, 0}.
Code Sample demonstrating the issue:
public class Point {
final double coordinates = {0, 0};
public void setCoordinate(int index, double value) {
coordinates[index] = value;
}
Expected outcome:
PMD reports a violation at line final double coordinates = new double[]{ 0, 0}, but that's wrong.
Running PMD through:
Gradle
