it is not, because as you mention later that you have to copy or rewrite
some of the BlueZ functions to fulfil the need for JSR-82. We should
talk about that and see what we can fixup in BlueZ.

What I also don't wanna use is somekind of "de.avetana.bluetooth" vendor
extensions. If something is not possible in pure Java JSR-82, sorry not
my bad ;)

And another important point for me is the coding style. The use of tabs
(8 spaces) is a must, because it makes the code easier to read and keep
developers from over-nesting.

The native interface should only be a wrapper. Let's talk about the
stuff and put some of it back to the Bluetooth library where it should
belong.

I know Java and I did a lot of programming with Java in the past, but I
haven't done anything in the last 5 years. May you write a small howto
for getting your stuff run. For me preferable with Debian Sid.
