> When you try to use an XmlRpcClient with an address containing an illegal 
> port number (>65535), you get a NullPointerException. After debugging I see 
> that the constructor call to java.net.InetSocketAddress throws a good 
> exception: IllegalArgumentException("port out of range"), but this is 
> silently ignored and null is returned from ReflectionSocketFactory.
> I suggest adding:
> if (cause instanceof IllegalArgumentException) {
>   throw (IllegalArgumentException) cause;
> }
> to give users of XmlRpcClient better error messages.
