Affects PMD Version:
7.11 to 7.15 (current)

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.
