[java] SwitchStmtsShouldHaveDefault triggered when default case is present

[karel1980]

Affects PMD Version:
6.40.0

Rule:
PMD.SwitchStmtsShouldHaveDefault
https://pmd.github.io/pmd-6.40.0/pmd_rules_java_bestpractices.html#switchstmtsshouldhavedefault

Description:

Code Sample demonstrating the issue:

enum State {
  ON, OFF
}

... switch(state) {
      case ON -> System.out.println("it is on");
      case OFF -> System.out.println("it is off");
      default -> System.out.println("it is neither on nor off - should not happen? maybe null?")
    }

Expected outcome:
No violation

** Actual outcome:**
PMD reports a violation at line switch(state), but that's wrong. That's a false positive.
