Bug 39746 Move super class constructor combo up.
Move the combo selection for the super class constructors to be above the field treeviewer for the "Create constructor using fields" source action.
org.eclipse.jdt.ui/ui/org/eclipse/jdt/ui/actions/CreateNewConstructorAction.java
label.setText(ActionMessages.getString("CreateNewConstructorSelectionDialog.sort_constructor_choices.label")); 
				GridData gd= new GridData(GridData.FILL_BOTH);
				label.setLayoutData(gd);
				
				final Combo combo= new Combo(composite, SWT.READ_ONLY);
				IMethod[] constructorMethods= StubUtility.getOverridableConstructors(fType);					
				
				for (int i= 0; i < constructorMethods.length; i++) {
					combo.add(JavaElementLabels.getElementLabel(constructorMethods[i], JavaElementLabels.M_PARAMETER_TYPES));
				}
				
				combo.setText(combo.getItem(0));
				combo.setLayoutData(new GridData(GridData.FILL_BOTH));
				combo.addSelectionListener(new SelectionAdapter(){
					public void widgetSelected(SelectionEvent e) {
						fSuperIndex= combo.getSelectionIndex();
					}
				});	
			} catch (CoreException e) {
			}
			return composite;
		}		
				
		public int getSuperIndex() {
			return fSuperIndex;
		}
	}
