This fixes the NPE, but the error message seems wrong. byte[] has a accessible constructor. For example byte[] map(byte[] b) works. BUILDER_NO_BUILD_METHOD_FOUND ("No build method \"%s\" found in \"%s\" for \"%s\". Found methods: \"%s\".") would fit better I think.

To be honest I was hoping for the message about mapping from non-iterable to iterable, because that one would fit better. Might spent some more time today to see if I can get that message to pop instead.

Thanks for the quick fix @Zegveld. Why are the changes in Type needed? The MethodRetrievalProcessor is happening earlier and I don't think that the changes in Type would be needed. Can you please revert those changes?

Seems like those changes were left over from initially tackling the NPE's. After doing the checks correctly at the MethodRetrievalProcessor these can indeed be reverted. I've reverted the changes to the Type class.

Thanks @Zegveld
