Affects PMD Version:6.41.0
Rule:ReturnEmptyCollectionRatherThanNull
Please provide the rule name and a link to the rule documentation:
https://pmd.github.io/latest/pmd_rules_java_errorprone.html#returnemptycollectionratherthannull
Description:
Hi, I think this rule should have reported warning about the following case, but it doesn't. I think this problem is caused by wrapped return null statemnet and it could be solved by matching.
Code Sample demonstrating the issue:
public int[] foo() {
if(true) {
return null; // should report a warning here, but no warnings
} else {
return null;
}
}
Expected outcome:
PMD should report a violation at line 3 or 5, but doesn't. This is a false-negative.
