the above would mean that in order to utilize the default message, 
we would need to explicitly call to 'setMessage()' with 'null' as 
a parameter, doesn't it?

maybe we should do the following instead:

     public void setMessage(String message) {
         super.setMessage(message);
     }

     public String getMessage() {
         return super.getMessage() != null ? super.getMessage() : constants.removeConfirmationPopupMessage();
     }

[of course, the above means that if someone would explicitly sets 
the message to 'null', the dialog would end up with the default 
message; but I think it is acceptable. so:
- if you want the default message: don't set message / set it to 'null'
- if you want an empty message: set message to an empty string
- if you want a message other than default: set it to whatever you want]
