Right now, the archive contains a JDK 1.0.2 code, which can still compile on versions 1.1.x of the JDK, with some compiler warnings. The "native" sound driver source inside will only compile and work on Linux and v. 1.0.2 of the JDK.
Like I say in the README file, I'll be happy to let another person coordinate and maintain this "project" instead of me. I, on my part, intended to invest a small amount of further work on it, if at all.
Enjoy!
