#1251 UnusedPrivateMethod false positives for boxing & unboxing arguments

[Ross]

If a private method is called with an unboxing Object argument, or a boxing primitive argument, then a false positive is generated for UnusedPrivateMethod.

I know that other people have reported false positives for UnusedPrivateMethod. I couldn't find an existing ticket for this issue, however, so I figured I submit it...

public class UnusedPrivateMethodFalsePositives {

    // UnusedPrivateMethod false positive
    private void prvUnboxing(final int i)     {}
    public  void pubUnboxing(final Integer i) {prvUnboxing(i);}

    // UnusedPrivateMethod false positive
    private void prvBoxing(final Integer i) {}
    public  void pubBoxing(final int i)     {prvBoxing(i);}

    // Correctly does not generate a warning
    private void prvPrimitive(final int i) {}
    public  void pubPrimitive(final int i) {prvPrimitive(i);}

    // Correctly does not generate a warning
    private void prvObject(final Integer i) {}
    public  void pubObject(final Integer i) {prvObject(i);}
}

Thanks - it has been covered by [#1228] and it will be fixed with PMD 5.1.3.
