#1484 [java] UnusedLocalVariable: false positive - parenthesis

[Jiří Pejchal]

import java.util.ArrayList;
import java.util.List;

public class Test {

public static void main(String[] args) {
    List<String> list = new ArrayList<>();
    list.add("first");
    list.add("second");

    int notEmpty = 0;
    for (String string : list) {
            if (!string.isEmpty()) {
                notEmpty++;
            }
    }

    System.out.println(list.size() + " (" + (notEmpty) + " not empty)");
}

}

notEmpty is reported as UnusedLocalVariable. If I remove the parentheses arround notEmpty everything is OK.

Thanks for reporting this bug. It will be fixed with PMD 5.3.8, PMD 5.4.2, PMD 5.5.0 and later.
