Causing dozens of FPs for us just in one PR.

• What language is this for? Java

See [SONARJAVA-4401] - Jira

Java 17 switches cause FP not just with -> methodCall(); syntax, but also when using switch blocks. e.g.

public class Main
{
    enum Kind { REGEXP, TAGS, REST }
    public static void main(String[] args) {
        Kind kind = Kind.REGEXP;
        switch(kind) {
            case REGEXP -> {
              yield ofNullable(portfolio.getSelectionExpression()).ifPresent(view::setRegexp); // FP
            }
            case TAGS -> ofNullable(portfolio.getSelectionExpression()).ifPresent(tags -> view.setTagsAssociation(getTags(portfolio))); // FP
            case REST -> view.setDef(true); // FP
            default -> {
            }
        }
    }
}
