Also, the C version has been downloaded and examined by everybody and
their dog, meaning it'll probably have fewer bugs, all else being equal.
It'll also most likely be more optimized and support more features.
And since the API is frozen, whenever a new version of Vorbis is
released, you'll be able to gain all it's advantages by simply
downloading the source and recompiling.
The JNI is made so that exactly the same C code will work with any Java
implementation on any platform. It should only require a recompile.
Given the portability of Ogg Vorbis, it should be very easy to write JNI
wrappers that compile with pretty much any Java implementation and C
Just a few thoughs,
