The below code is using long literal with yield and it should compile successfully. However, it reports compilation error.

class Test {
    public void check() {
        var num = switch (1) {
            case 1:
                yield 0L; //Works with yield 0.0f, 0.0d and (long)0L
            default:
                yield 0;
        } ;
    }
}

Result:

Test.java:5: error: not a statement
                                        case 1 : yield 0L;
                                                 ^
Test.java:5: error: ';' expected
                                        case 1 : yield 0L;
