Possible != Easy. There are quite a lot of guys who took that path and its totally possible. Unfortunately a great example of what can go wrong is now available with RoboVM, this turned out to be such a huge effort to maintain that they literally closed their source. Now the OSS community is trying to fork the code and because the code is so complex its really hard to do that. Even if Codename One goes belly up or is acquired by a closed source company in the future you will probably be able to still work with the code without a problem. There are a couple of other advantages with this approach: 1. Use the native tooling (e.g. profilers etc.) which are pretty amazing on iOS. 2. Just write Objective-C/SWIFT code for various features. This is hugely convenient when adopting features from the latest version of iOS.
