The two upgrades patch some vulnerabilities and increase reliability and compatibility. So, if you have an earlier version of the software, it`s better that you upgrade.
Apple says in the notes for Java for OS X Lion Update 1 that it provides “improved compatibility, security and reliability.” The update is 62.53 MB is size, and Apple recommends shutting down all browsers and Java applications prior to installing the update.
The notes for Java for Mac OS X 10.6 Update 6 are pretty much identical. The 10.6 update is a bit larger at 75.45 MB.
Both of the updates bump Java SE 6 to version 1.6.0_29. The Java update fixes some security bugs. The previous version of Java used to execute codes outside of the Java Sandbox. For further information and details on the update you can visit the Sun’s Website and look for security content.
You can download these updates via Software Update on your Mac and Apple’s Support Downloads website.
We get two software updates today, one for OS X Lion and the other for OS X Snow Leopard. Apple has released Update 1 for Java for OS X Lion, as well as Update 6 for Java for Mac OS X 10.6 (Snow Leopard).
