The if/else to switch clean-up has been enhanced to properly handle the case where the value can be null. In the if/else statement, this is handled intrinsically either by an else statement or falling through the if/else if, but when converting to a switch statement, either the switch must be embedded in an if statement to test for null or for Java 21 or above, a <b>case null</b> statement needs to be added.
