Bug 136222

in NB6.1,create a class file which named "User.java" and enter codes like this:
public class User{
   private String username;
   private String password;

   public String getUsername(){
      return username;
   }
   public void setUsername(String username){
      this.username=username;
   }

}
choose "Refactor->Encapsulate Fields" menu, in the refactor dialog box,
choose all the fields to generate setter/getters.
After do  above operations,IDE sometimes popup a error dialog(please see the attachment),
and  does  not generate the Setter/Getter method for field password.

I test with other class,it is seemed that if your have a  Setter/Getter methods for a field,
the IDE can not generate  Setters/Getters for the remain fields.
