The Standard Service Life of Java 5 expired on Friday, October 30th. This is not really tradic, because Sun provides a Java SE 6 since December 2006. But on the other side on Mac OS X (up to 10.5. Leopoard) the default JRE is Version 5.0. 
Apple only published a Version 6 for 64 bit Intel processors. So many desktop applications still uses Java 5 as basis. It would be interessting, what Apple will do, if critical bugs in Java 5 would be found.
