Hi

I've got a language question when attempting to implement the Parameter
Constants pattern as written in a javaworld article (see:
http://www.javaworld.com/javaworld/javatips/jw-javatip50.html).
Basically this pattern is a way of providing type safety for constants
defined in a class.   A sample implementation is shown below:

public class ConTest implements ConTest.Parameters {

 public interface Parameters {
  WeekDay SUNDAY = new WeekDay(0);

  final class WeekDay {
   private final int weekday;

   private WeekDay(int i){
    weekday = i;
   }
  }
 }

 public ConTest(Parameters.WeekDay weekday){
 }


 public static void main(String[] args){
  ConTest con = new ConTest(ConTest.SUNDAY);
 }
}

The problem is that when implemented in JBuilder I get a compilation
error  for the line WeekDay SUNDAY = new WeekDay(0); whereby the
compiler complains

"variable this$0 might not have been initialized"

Yet in comparison, compiling & running with JDK 1.1.6 there are no
problems.

Is this a bug in the compiler for JBuilder (version 2.0) ?

Any comments are most welcome
