#1428 [java] UnusedPrivateField: False positive when local variable hides member variable

[Patrick McEvoy]

If a member variable is hidden by a local variable then PMD thinks the member variable is not used.

Example code to reproduce the issue
public class IssueUnusedPrivateField {

private static Object helper;   // PMD warns unused

@BeforeClass
public static void setUpClass() {
    helper = new Object();
}

@Test
public void testSomething() {
    String str = helper.toString();     // used here
    System.out.println("str = " + str);

    String helper = "some new string";  // hidden here
    System.out.println("helper = " + helper);
}

}

Thanks!
This will be fixed with PMD 5.3.6 and later.
