STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
Compile the attached source code.


EXPECTED VERSUS ACTUAL BEHAVIOR :
EXPECTED -
The program compiles successfully
ACTUAL -
> javac Yield.java
Yield.java:5: error: not a statement
        yield !1;
        ^
Yield.java:5: error: ';' expected
        yield !1;
             ^
2 errors


---------- BEGIN SOURCE ----------
class Yield {
  public static void main(String... args) {
    int value = switch (1) {
      default -> {
        yield !1;
      }
    };
  }
}

---------- END SOURCE ----------

CUSTOMER SUBMITTED WORKAROUND :
Wrap the expression in ()

FREQUENCY : always
