How to reproduce:
1) Create ServerMain
2) Create 2 implementation. 
For instance: First a.AImpl and Second: b.AImpl - they must have the same 
class name but different package
3) Add Servant under RootPOA and 
specify its class name as a.AImpl
4) NOTE - Constructor of this class is 
automatically filled.
5) Press OK
6) Customize created Servant 
node
7) Select second class name (b.AImpl)
8) Press Close
9) Look at 
ServerMain source file in editor
10) ERROR - Constructor is not 
updated!

In the file there is this line:
b.AImpl myServant = new 
a.AImpl();

But there should be this line:
b.AImpl myServant = new 
b.AImpl();
