Oracle ADF: SkinFactory is not working correctely in JDeveloper 12.1.3

I use the code below to populate my skin list and give the user the possibility the change the skin at runtime.

public List getSkinChoices() {
    List choices = new ArrayList();
    String skinFamily = null;
    String skinLabel = null;
    SkinFactory sf = SkinFactory.getFactory();
    FacesContext context = FacesContext.getCurrentInstance();
    for (Iterator i = sf.getSkinIds(); i.hasNext();) {
        String skinID = (String) i.next();
        Skin skin = sf.getSkin(context, skinID);
        skinFamily = skin.getFamily();
        skinLabel = skinFamily;
        if (skin.getRenderKitId().indexOf("desktop") > 0 ) {
            choices.add(new SelectItem(skinFamily, skinLabel));
        }
    }
    return choices;
}

Now that i am using Jdev 12.1.3 the method sf.getSkinIds(); is deprecated. The method is no more loading all skin as usually

Could somebody directes me to the new implementation way? Is there any alternativ to get all availlable skins?

NB: The code about loads all availlable skin in Jdev 12.1.2.
Thanks

The SkinFactory class is part of the Trinidad API and according to its javadoc, you have to:

Use SkinProvider#getSkinMetadata() to get the list of skins supported.

So, you have to do something like this:

Collection<SkinMetadata> supportedSkins = SkinProvider.getSkinMetadata(context);
Iterator<SkinMetadata> iterator = supportedSkins.iterator();
while (iterator.hasNext()) {
    SkinMetadata next = iterator.next();
    skinFamily = next.getFamily();
    //etc.
}
