JDK 1.4 MR (marketing release)
As far as the release notes report there is no difference between this and the release candidate. In what seems to have been a reaction to VS .Net being launched yesterday. It doesn't seem to have made a blip on the major news services while there heaps about MS security, hardware and .Net. There is three bytes difference in the tools.jar I wonder if it's "-rc" that's missing.
