Sun's VM returns null for the boot loader.. here's an example:

    $ cat > xx.java
    public class xx {
        public static void main(String[] args) throws Exception {
            System.out.println(Object.class.getClassLoader());
        }
    }
    ^D
    $ javac xx.java && java xx
    null
    $ java -version
    java version "1.4.2-p5"
    Java(TM) 2 Runtime Environment, Standard Edition (build 
1.4.2-p5-archie_18_nov_2003_16_43)
    Java HotSpot(TM) Client VM (build 1.4.2-p5-archie_18_nov_2003_16_43, mixed 
mode)

Are there some cases where Sun's Class.getClassLoader() doesn't
return null but other VM's do?
