I have one for 4.4.8. I'm not sure about the newest. However I can ask the guy 
that did it for me to do a newer build. I guess it will take about a week. 
I'll contact it on monday. 

If someone else in the list has one compiled the package for windows with jni, 
please shout. :)

The jar is just one for all the machines, whereas the dependency lies in 
the .dll, .so or .jnilb for windows, linux and mac (however no one compiled 
it for mac yet).

No, but I can send it to you.
