Packaging, installation, and licensing changes

I have recently installed JDK 1.4.1: this has revealed a couple of problems/inconstencies. The new JDK release appears to fix some problems with regular expression handling and with use of collations. This means that some of my tests produce subtly different results. In one or two cases the new results are clearly wrong, which means that my code was relying on the incorrect JDK 1.4.0 behavior. I have made adjustments where it seems appropriate, but particularly with collations, it is not always obvious what the right answer is.
