#1318 UnusedCode/UnusedPrivateMethod False Alarm

[dmgob]

Example that shows the bug:

Class 1:

public class Parent {  public void parentMethod() {} }

Class 2:

public class Child extends Parent { public void childMethod() {} }

Class 3:

public class Client {

  public void clientMethod() {
    final Child c = new Child();
    privateMethod1( c );
    privateMethod2( c );
  }

  private void privateMethod1( Parent p ) {
    p.parentMethod();
  }

  private void privateMethod2( Child c ) {
    c.childMethod();
  }

}

Compiled with Java 6.

The problem is that "privateMethod1", the one invoked with a var of the Child
type but declared with the supertype, is flagged as "unused" (wrong). The method
privateMethod2, for which the types matched, is not flagged (correct).

Thanks for the bug report.
I can reproduce your example with PMD 5.2.1 (without auxclasspath option) - but it doesn't show up anymore with PMD 5.2.2 nor with 5.2.3 (regardless of the auxclasspath option).
Can you verify, which version of PMD you are using?
Regards,
Andreas
