The release updates Java SE 6 to version 1.6.0_07, J2SE 5.0 to version 1.5.0_16, and J2SE 1.4.2 to 1.4.2_18. The update is available through Software Update and the Apple Support website. > > The parts in bold seem contradictory. When I read things like Updates J2SE 5.0 to version 1.5.0_16 it seems like more of a downgrade to me. Going from 5.0 to version 1.50_16 WTH?!!" I recently learned that my Mac Mini included several versions of Java. By default it runs some version of Java 5. I tried to run the Glassfish gem, got an error about how the gem required Java 6, and did the most reasonable thing I could think of: bitch about Apple on Twitter. A minute later a friend replied with instructions on how to select among the different Java's available. Happiness! The different versions are for 32- and 64-bit Java 5 and 6 (though Java 6 is only available for 64-bit OS X) So, an upgrading of the installed Javas could very well involve multiple, seemingly incompatible, versions. -- James Britt www.jamesbritt.com - Playing with Better Toys www.ruby-doc.org - Ruby Help & Documentation www.rubystuff.com - The Ruby Store for Ruby Stuff www.neurogami.com - Smart application development
