Affects PMD Version:6.42.0

Rule:StringInstantiation

Please provide the rule name and a link to the rule documentation:
https://pmd.github.io/latest/pmd_rules_java_performance.html#stringinstantiation

Description:

Hi, I found a false negative about the rule StringInstantiation. Please read the following code example. PMD should have reported a warning at line 5 because this line create a String object by new. Hence, I think this is a false negative. Thanks for your kind consideration.

Code Sample demonstrating the issue:

String getLiteral() {
    return "foo";
}
String foo() {
    return new String(getLiteral()); // should report a warning at this line
}

Expected outcome:Warning

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