-Xswitchcheck doesn't appear to be enabled in 1.4beta2

Name: rmT116609 Date: 09/06/2001


java version "1.4.0-beta2"
Java(TM) 2 Runtime Environment, Standard Edition (build 1.4.0-beta2-b77)
Java HotSpot(TM) Client VM (build 1.4.0-beta2-b77, mixed mode)


Create Test.java (unnecessary really, but...):

public class Test
{
    public static void main (String [] args)
    {
        int x = 5;
        
        switch (x)
        {
            case 0:
                System.out.println ("0");
            case 1:
                System.out.println ("Oops");
                break;
        }
    }
}

Try
javac -Xswitchcheck Test.java

Results:

javac: invalid flag: -Xswitchcheck

According to the 1.4beta2 docs the above should have worked.
