Affects PMD Version: pmd:3.19.0:check

Rule:UnusedPrivateMethod

Description:
Calling a private method that accept one parameter of type Number (superclass of autoboxing-type Integer)
Code Sample demonstrating the issue:

// ...foo(2);}privatevoidfoo(Numberbar) {System.out.println(bar);}

Expected outcome:

PMD reports a violation at line 124, but that's wrong. That's a false positive.

Running PMD through:Maven

Workaround:

Cast the parameter to Number will work:

// ...foo((Number)2);}privatevoidfoo(Numberbar) {System.out.println(bar);}
