New Instance with optional number param gets NaN

[matej-snivam]

Hello,

when creating new instance of starling Asset Manager with constructor like this:
public function AssetManager(scaleFactor:Number=1, useMipmaps:Boolean=false)
{
the scaleFactor gets NaN when it should be 1

        injector.map(AssetManager).toSingleton(AssetManager);
        injector.getInstance(AssetManager);

this is how I get it for debugging purpose
