Apple today released a pair of software updates for users of Mac OS X Snow Leopard and Leopard, delivering updated versions of Java containing the latest performance and security fixes.

- Java for Mac OS X 10.6 Update 1 weighs in at 78 MB and requires Mac OS X 10.6.2.

Java for Mac OS X 10.6 Update 1 delivers improved reliability, security, and compatibility for Java SE 6. Java for Mac OS X 10.6 Update 1 supersedes the previous Java for Mac OS X 10.6.

This release updates Java SE 6 to version 1.6.0_17. This release is only for Mac OS X 10.6.2 or later versions of Mac OS X 10.6. This release of Java SE 6 is available on Intel-based Macs only.

Details of the security content included in the update can be found in the associated support document.

- Java for Mac OS X 10.5 Update 6 weighs in at 122 MB and requires Mac OS X 10.5.8.

Java for Mac OS X 10.5 Update 6 delivers improved reliability, security, and compatibility for J2SE 5.0 and Java SE 6. Java for Mac OS X 10.5 Update 6 supersedes all previous updates of Java for Mac OS X 10.5.

This release updates J2SE 5.0 to 1.5.0_22, and updates Java SE 6 to 1.6.0_17. J2SE 1.4.2 is no longer being updated to fix bugs or security issues and is therefore disabled by default in this update. This release is only for Mac OS X 10.5.8 or later versions of Mac OS X 10.5. This release of J2SE 5.0 supports all Intel and PowerPC-based Macs. Java SE 6 is available on 64-bit Intel-based Macs only.
