CodenameOne Final Variable error with iOS - variables

Question

I have a piece of code working as expected in Android but not in iOS. Problem is the value of the final variable 'nombre' which in Android gets the expected value, whereas in iOS it gets a different one randomly chosen from the list (specified in codesnippet provided)
public AsignarNombreCDF(){
this.departamentoId = AdministradoresApp.departamentoId;
this.setLayout(BoxLayout.y());
this.setTitle("Asignar Nombre a CDF");
TopBarUtils.addMenuToTopbar(this);
TopBarUtils.addCommandToTopbarMenu(this, "Inicio Departamento", e->{new MenuDepartamento(departamentoId).show();});
try {
Map m = Utils.consultaWebService("newfoldernames", new Object[]{"department", departamentoId});
String folderNameMatrix = (String) m.get("FolderNameMatrix");
Map m_ = (Map) JSONUtils.fromJsonString(folderNameMatrix);
Iterator it = m_.keySet().iterator();
while(it.hasNext()){
String k = (String) it.next();
final String nombre = (String) m_.get(k);
Button b = new Button(nombre);
b.addActionListener(e->{cargarFotos(nombre);});
this.add(b);
}
int y = 2;
} catch (Exception ex) {
Utils.gestionaExceptionUi(ex);
}
}
Problem is that the final variable nombre seems not to assign correctly to the value passed to the button listener. This as already said, only happens in IOS and not in Android, where we never get a mismatch. Any chance that the iOS build system might oversee this situation?. Any ideas how to overcome the problem?
Regards.
