Rule Set:
UnusedPrivateMethod
Description:
A private method with a signature containing a map as argument, and with that map having a list of doubles as values using a primitive type, e.g. double[], PMD unexpectedly reports an unused private method.
Code Sample demonstrating the issue:
public class Foo {
public Foo() {
Map<String, double[]> map = new LinkedHashMap<>();
addToMap(map);
}
private void addToMap(Map<String, double[]> map) {
map.put("foo", new double[]{0., 1.});
}
}
Running PMD through: Gradle (Gradle 3.5, tried with default pmd plugin as well as toolVersion = '5.8.0')
PMD does not complain when using the boxed variant:
// This is ok!
private void addToMap(Map<String, Double[]> map) {
// ...
}
Is this better/the preferred style anyway?
