steps to reproduce:
0. create project in design center
1. create class diagram
2. add pattern to the diagram
3. bind class role with the pattern
4. add operation 'public void op( Vector par)' to the class
5. propagate pattern to design center
6. check operation in design center
Vector is replaced with int

The same for attributes, try to add private String log attribute to class role
And for return types, add operation with String return type, check types after
propagation, return type is replaced with void, attribute type is replaced with int.
