Apple made a huge announcement by releasing Java updates for Mac OS 10.6 Snow Leopard and Mac OS 10.5 Leopard. Java for Mac OS X 10.6 Update 4 weighs in at 74 MB and requires Mac OS X 10.6.4 or later; it delivers improved compatibility, security, and reliability by updating Java SE 6 to 1.6.0_24.
Java for Mac OS X 10.5 Update 9 weighs in at 119 MB and requires Mac OS X 10.5.8 or later; it delivers improved compatibility, security, and reliability by updating J2SE 5.0 to 1.5.0_28, and updating Java SE 6 to 1.6.0_24 for 64-bit capable Intel-based Macs. J2SE 1.4.2 is no longer being updated to fix bugs or security issues and remains disabled by default in this update.
However the updates are available now using the download links above or via Software Update. Note that after Snow Leopard and Lion, future versions of Mac OS X will not necessarily ship with an Apple-provided JDK; rather, the Open JDK project will be delivering Java for the platform.
