JavaCard does not support clone() for arrays, which causes problems for enums. 
It would be nice if javac could generate different code for the values() method that does not rely on array.clone().

For example, replace the following:
    public static Color[] values() {
        return (Color[]) $VALUES.clone();
    }

with this:
    public static Color[] values() {
      Color[] copy = new Color[$VALUES.length];
      System.arraycopy($VALUES, 0, 
                       copy, 0, 
                       $VALUES.length);
      return copy;
    }

N/A

Could make the alternate code be dependent on whether java.lang.Cloneable is on the bootclasspath.

Per 6627366, it looks like Cloneable and Serializable have to be on the class path if a program uses Java arrays. Therefore, it is proposed to refine the test of whether or not to use clone() to 
- Cloneable not found
- Cloneable not public
