Affects PMD Version:
6.39.0
Rule:
AddEmptyString
Please provide the rule name and a link to the rule documentation:
https://pmd.github.io/latest/pmd_rules_java_performance.html#addemptystring
Description:
PMD should have reported a warning at line 3, because String variable test adds an empty string, but it doesn't. This can lead to performance issue. So, I think it is a false negative. Thanks for your consideration.
Code Sample demonstrating the issue:
public void func() {
final String var = "";
String test = var + "123"; // should report a warning here
}
Expected outcome:
PMD should report a violation at line 3, but doesn't. This is a false-negative.
