Steps to reproduce:

- Reverse engineer the 'public void testStaticImport( double theta )'
   method from 'TestStaticImport' class and create a Sequence diagrams:
  ---------------------------------------------------------------------
  import static java.lang.Math.PI;
  import static java.lang.Math.cos;

  public class TestStaticImport {
    
    public void testStaticImport( double theta ){
        double r = cos(PI * theta);
    }
  }
  ---------------------------------------------------------------------
  There is the 'public void cos(PI unnamed)' message which has 'self'
  Receiving Lifeline instead of ':Math' message
