make more available the url loaded by the webview

I want to get the url of the web page displayed by the webview.

When the user clicks on a web link, I can catch the MouseEvent and get the url into the handler.

But the user can go back, directly, through right-clicking into the WebView. And then, it's harder to get the url.

Well, I have discovered I can add a listener to the 'state' property.

webEngine.getLoadWorker().stateProperty().addListener(
new ChangeListener<State>() {
@Override
public void changed(ObservableValue<? extends State> ov,
State oldState, State newState)
{
System.out.println("stateProperty.ChangeListener: newState=" + newState + " message=" + webEngine.getLoadWorker().getMessage());
}
});
 
Then, when the user goes back, the outputs are:

stateProperty.ChangeListener: newState=SUCCEEDED message=Loading http://news.google.fr/nwshp?hl=fr&tab=ln
stateProperty.ChangeListener: newState=SCHEDULED message=Loading http://news.google.fr/nwshp?hl=fr&tab=ln
stateProperty.ChangeListener: newState=RUNNING message=Loading http://news.google.fr/nwshp?hl=fr&tab=ln
stateProperty.ChangeListener: newState=SUCCEEDED message=Loading http://maps.google.fr/maps?hl=fr&tab=wl
stateProperty.ChangeListener: newState=SCHEDULED message=Loading http://maps.google.fr/maps?hl=fr&tab=wl
stateProperty.ChangeListener: newState=RUNNING message=Loading http://maps.google.fr/maps?hl=fr&tab=wl
stateProperty.ChangeListener: newState=SUCCEEDED message=Loading http://www.google.fr/advanced_search?hl=fr
stateProperty.ChangeListener: newState=SCHEDULED message=Loading http://www.google.fr/advanced_search?hl=fr
stateProperty.ChangeListener: newState=RUNNING message=Loading http://www.google.fr/advanced_search?hl=fr
stateProperty.ChangeListener: newState=SUCCEEDED message=Loading http://www.google.fr/
stateProperty.ChangeListener: newState=SCHEDULED message=Loading http://www.google.fr/
stateProperty.ChangeListener: newState=RUNNING message=Loading http://www.google.fr/
stateProperty.ChangeListener: newState=SUCCEEDED message=Loading http://www.google.fr/advanced_search?hl=fr
stateProperty.ChangeListener: newState=SCHEDULED message=Loading http://www.google.fr/advanced_search?hl=fr
stateProperty.ChangeListener: newState=RUNNING message=Loading http://www.google.fr/advanced_search?hl=fr
stateProperty.ChangeListener: newState=SUCCEEDED message=Loading http://www.google.fr/

So, I can get the url through the 'message' property.

But I need to parse the 'message' property's value.

Is it possible to split the 'message' property ?
into 2 properties, one containing the 'Loading' part (or whatever is the first part of the message's value), and another one containing only the url.
