No arguments in DIVs favour from me.

Indeed, JNA looks impressive, it requires less effort than directly using JNI. But in any case you'd loose the platform independence, and since you're probably only using a small part of it, you might consider translating what you actually need. |

It comes down to what you need it for. Its main strength is the easy maintainability of the transform, and writing your own parser generally obliterates that.
