Description milanka 2017-09-08 12:01:44 UTC
public class Test {
    private int a;
    private int b;
    private int c;

    public Test(int a, int b, int c) { // "c" is not marked as unused
        this.a = a;
        this.b = b;

In the case above I have added "c" to parameters and as a private variable, but forgotten to do the assignment. Of course if I had marked all variables as final I would have noticed the error, but showing a warning would nevertheless be a good thing in my opinion.

Issue is related, but I think this issue has less potential problems.
