#1287 UnusedPrivateMethod returns false positives for Superclass

[Muminur Choudhury]

I tried to update from PMD 5.1.1 to 5.2.1 but I have encountered a number of UnusedPrivateMethod false positives.

This is a simple example to demonstrate one issue

public class SuperClassFalsePositive {

    public void myPublicMethod() {
        throw convertToUnchecked(new MyException("Something Bad Happened"));
    }

    private IllegalArgumentException convertToUnchecked(Exception e) {
        return new IllegalArgumentException(e);
    }

    private static class MyException extends Exception {
        public MyException(String message) {
            super(message);
        }
    }
}

With PMD 5.2.1 I get

PMD Failure: SuperClassFalsePositive:11 Rule:UnusedPrivateMethod Priority:3 Avoid unused private methods such as 'convertToUnchecked(Exception)'..

With PMD 5.1.1 no issues reported.

Not reproducible with 5.2.2(-SNAPSHOT) anymore - with and without auxclasspath.

Probably fixed already with [#1281], [#1278] or [#1276].
