[java] UseArrayListInsteadOfVector ignores Vector when other classes are imported

[ghost]

Affects PMD Version:6.47.0

Rule:UseArrayListInsteadOfVector

Please provide the rule name and a link to the rule documentation:
https://pmd.sourceforge.io/pmd-6.50.0/pmd_rules_java_performance.html#usearraylistinsteadofvector

Description:
Hi, I found a false negative about the rule UseArrayListInsteadOfVector, please read the first code example below. PMD should have reported a warning in line 5, but it does not. However, in the second code example, PMD can report the warning as expected. Hence, I think this is a false negative. Thank you!

Code Sample demonstrating the issue:

First code example

import org.Annotation;
@Annotation
public class C {
    void x() {
        Vector v = new Vector();  // should report a warning in this line, but no warnings
    }
}

Second code example

public class C {
    void x() {
        Vector v = new Vector();  // Can detect the warning
    }
}

Expected outcome:

PMD should report a violation at line 5, but doesn't. This is a false-negative.

Thanks for the report.
It is not the Annotation, that trips the rule, but the other import, e.g. here we also don't detect Vector:

import some.OtherClass;

public class C {
    void x() {
        java.util.Vector v = new java.util.Vector();  // Can detect the warning
    }
}

Note: your example doesn't really compile, because you didn't import "java.util.Vector". As soon as you add import java.util.Vector; additionally, it works.

Hi, thanks for your reply. I may ignore the import when submitted the issue, and it seems that problem is not only casuse by the annotation and has been fixed now.
