> If we have class Foo with method:
> public class Foo {
>    public void bar(Object a, String b) {}
> }
> then MethodCall fails if we invoke:
> dispatcher.callRemoteMethods(null, "bar", new Object[] {"hello", "world"}, new Class[]{String.class,String.class}, ...);
> because the first formal parameter of foo() is an Object and the arg a String, and we do an equals() on the 2 classes. 
> Solution: use Class.isAssignableFrom(Class)
