Also I'll completely drop the Java5 support, so I wouldn't suggest you base anything on the current sandbox code any time soon. Anyhow, it's still in active development, and the original plan for replacing Daemon and Tomcat Native core functionality still stands, but since lots changed in JVM area since sandboxed, I had to rethink of few concepts, especially about using core Unsafe API which offers much higher JNI performance. Ping me back in a month or just watch the SVN activity, and I'll be able to give you more info then. Worse case? It might even go to the attic before exiting the sandbox. Sometimes I find developing inside ASF so frustrating, that I'm not sure I wish to do that again. It's not the same place I remember it was a decade ago.
