StatementSwitchToExpressionSwitch jdk17 doesn't work

In this reproducer https://github.com/delanym/error-prone-reproducer

I took an example from https://errorprone.info/bugpattern/StatementSwitchToExpressionSwitch

``` java
enum Suit {HEARTS, CLUBS, SPADES, DIAMONDS};

private void foo(Suit suit) {
switch(suit) {
case HEARTS:
System.out.println("Red hearts");
case DIAMONDS:
System.out.println("Red diamonds");
case SPADES:
// Fall through
case DIAMONDS:
bar();
System.out.println("Black suit");
}
}
```

fixed the duplicate case (!), ran it through EP 2.18.0
with command `./mvnw`
and it didn't fail.
