O que seria este código?

public class Teste
{
	/**
	 * @param args
	 */
	public static void main(String[] args)
	{
		try
		{	
			Class.forName(args[0]).getMethod("main",new Class[]{String[].class}).invoke(new Object(),new Object[]{args});
		}
		catch (IllegalArgumentException e)
		{
			JOptionPane.showMessageDialog(null,"Illegal Arguments");
		}
		catch (IllegalAccessException e)
		{
			JOptionPane.showMessageDialog(null,"Illegal Access");
		}
		catch (InvocationTargetException e)
		{
			JOptionPane.showMessageDialog(null,"Invocation Target");
		}	
		catch (SecurityException e)
		{
			JOptionPane.showMessageDialog(null,"SecurityException");
		}
		catch (NoSuchMethodException e)
		{
			JOptionPane.showMessageDialog(null,"NoSuchMethodException");
		}
		
		catch (ClassNotFoundException e)
		{
			JOptionPane.showMessageDialog(null,"ClassNotFoundException");
		}
	}
}
