Re: alternative to my ClassLoader hack

I have my version working now. The secret is to poke the object made
with the new classloader reflectively. I guess the exception I get
above is related to the fact that MyClassLoader is loaded by two
different classloaders, and therefore one class type isn't the same as
the other. Weird, but true.

This version does pass the first MyClassLoader.class to the second,
and then compares the two class types and determines they are not
equal, as expected. I think this program and Stevens programs are
equivalent, showing that both ideas are valid.

class Launcher
{
    public void launch()
    {
        System.out.println( "Classloader: " + getClass().
                getClassLoader() );
    }
}

class FubarLoader extends URLClassLoader
{
    public FubarLoader( URL[] urls )
    {
        super( urls );
    }

    @Override
    public Class<?> loadClass( String className )
            throws ClassNotFoundException
    {
        System.out.println( "finding " + className );
        if( className.startsWith( "fubar" ) ) {
            Class<?> c = null;
            try {
                c = findClass( className );
            }
            catch( ClassNotFoundException ex ) {
            }
            if( c != null ) {
                System.out.println( "findClass got it" );
                return c;
            }
        }
        System.out.println( "trying super class..." );
        return super.loadClass( className );
    }
}
