[java] AssignmentInOperand false positive in 7.17.0 for case blocks in switch statements #6092
Description
Affects PMD Version:
7.17.0
Rule:
AssignmentInOperand
Please provide the rule name and a link to the rule documentation:
AssignmentInOperand
Description:
The fix for issue #3434 causes version 7.17.0 to flag assignment in case assignments.
Code Sample demonstrating the issue:
public final class FPTestAssignmentInOperand {
private FPTestAssignmentInOperand() {}
public static void main(String[] args)
{
String a = null;
String b = null;
String c = null;
switch (args[0])
{
case "A" -> a = "a";
case "B" -> b = "b";
case "C" -> c = "c";
default -> {/*Do Nothing*/}
}
System.out.println("A: " + a + ", B: " + b + ", C: " + c);
}
}Expected outcome:
PMD reports a violation at lines 12,13, and 14, but that's wrong. That's a false positive.
