Description:
Coke build: 2006.05.09

Steps to reproduce:

- Create a java application
- Add 'pack' package into the java application
- Add 'ListClass' and 'TreeClass' under the package:
  -----------------------------------------------------------
  package pack;
  public class ListClass<Element> {
    
    Node head;
    
    private class Node{

        Node next;
        Element element;
        
        Node(Element element, Node next){
            this.element = element;
            this.next = next;
        }
        
        Element getElement(){
            return element;
        }
        
        Node getNext(){
            return next;
        }
    }
  }


  -----------------------------------------------------------
  -----------------------------------------------------------
  package pack;
  public class TreeClass<Element> {
    
    private Node root;

    private class Node{
        
        Node leftNode;
        Node rightNode;
        Element element;
        
        Node(Element element){
            this.element = element;
        }
        
        Element getElement(){
            return element;
        }
        
        Node getLeftNode(){
            return leftNode;
        }
        
        Node getRightNode(){
            return rightNode;
        }
    }
  }

  -----------------------------------------------------------

- Create UML Reverse Engineering project associated with the java application
- Select 'Model|pack|TreeClass' node under the UML project and invoke
  'Generate Dependency Diagram'
- There is incorrectly relationship between 'TreeClass' and 'Node' from
'ListCLass'  on the class diagram.



Some times 'Node' Datatype is created under UML Model node and incorrectly
relationship between 'TreeClass'
and 'Node' Datatype is shown on the dependency diagram.

This is an exception from IDE log file:
