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
Usage: javac <options> <source files>
where possible options include:
  -g Generate all debugging info
  -g:none Generate no debugging info
  -g:{lines,vars,source} Generate only some debugging info
  -O Optimize; may hinder debugging or enlarge class file

  -nowarn Generate no warnings
  -verbose Output messages about what the compiler is doing

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