TypeTestUtil.isA confuses type Character from same package with java.lang.Character

[Luro02]

Affects PMD Version: 7.0.0-rc3

Description:

TypeTestUtil.isA is used by PrimitiveWrapperInstantiationRule to check if a type is a primitive like a Character. The implementation is not correct, because with this code:

src/Character.java

public class Character {
    public Character(String string, Integer integer) {}
}

src/Test.java

public class Test {
    public void execute() {
        Character character = new Character("a", 1);
    }
}

the lint reports the new Character line, which is wrong. The code does compile and the constructor does not exist in java.lang.Character.

@Luro02 how are you running PMD? This seems to be caused simply because you are not setting the auxclasspath properly https://docs.pmd-code.org/latest/pmd_languages_configuration.html#java-language-properties

Lacking the auxclasspath, it can't tell which classes are available beyond the JRE

I did not set that, seems to have been the issue
