Affects PMD Version:
Rule:UseStringBufferForStringAppends
Please provide the rule name and a link to the rule documentation:
https://pmd.github.io/latest/pmd_rules_java_performance.html#usestringbufferforstringappends
Description:
Hi, I have encountered a false negative when PMD tried to detect UseStringBufferForStringAppends. Below is the test case for reproducing this false negative:
Code Sample demonstrating the issue:
public void testUseStringBufferForStringAppends() {
String a;
a = "foo";
a += " bar"; // Should report a warning here
}
Expected outcome:Warning
PMD should report a violation at line 4, but doesn't. This is a false-negative.
Running PMD through: [Maven]
