#1286 UnusedPrivateMethod returns false positives for varags and enums

[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 in relation to methods with varags.

This is a simple example I have come up with

public class VaragsFalsePositive {

    enum Sizes
    {
        TINY,
        MEDIUM
    }

    public boolean containsTiny(){
        return hasTiny(Sizes.MEDIUM, Sizes.TINY);
    }


    private boolean hasTiny(Sizes... sizes) {
        for (Sizes size : sizes) {
            if (size==Sizes.TINY) {
                return true;
            }
        }
        return false;
    }
}

With PMD 5.2.1 I get :

PMD Failure: VaragsFalsePositive:18 Rule:UnusedPrivateMethod Priority:3 Avoid unused private methods such as 'hasTiny(Sizes...)'..

With PMD 5.1.1 no issues with the above.

This will be solved with 5.2.2.

Probably a duplicate/similar case like [#1281], [#1276]

It's actually failing, in case auxclasspath option is in use.

Thanks for catching this! It will be fixed with 5.2.2.
