The point is, Java is more portable, but not a lot more portable as it
claims to be (or used to claim to be). As a packager at Fedora I came
across many JNI based libraries, such as jjack (Java API for Jack),
libswt3 (I think this is a graphical toolkit). There are also Java
implementations (with JNI) of fluidsynth, portmidi. There is plenty of
other ones, but since I don't package those and since I am simply not
that much interested in, I can't tell them right out of my head.
