I didn’t find any clear instructions on upgrading the JDK on OS X so I thought I’d share my findings.
Hi, I'm using a G5 running 10.5.8 and just updated to Vuze 5.0.0.0. According to Vuze I'm on Java 1.5.030. Although Vuze runs, it complains that some of it's plugins need a newer version of Java. So I downloaded JavaForMacOSX10.5Update6.pkg. However, when I try to install it, it says there is already a newer version of Java installed.

Mac OS X 10.5 Leopard is a very reliable operating system, providing a lightweight environment with a sleek and user-friendly interface to handle all. If you have not yet installed Apple's Java OS X 2012-006 update, then you are still using a version of Apple Java 6 that includes the plug-in and the Java Preferences app. See 'Note for Users of OS X that Include Apple Java 6 Plug-in'. There can be multiple JDKs installed on a system, as many as you wish.
First off, apparently Software Update does not automatically update the JDK. You have to manually download and run the updates. There are four updates to “Java for Mac OS X 1.5”. Since I couldn’t tell whether they were cumulative or not, I just downloaded and installed each one in sequence:
Java 1.8.0 Download
Now you’d think you’d be done, but those updates only install JDK 1.6—they don’t make it the default. The way I did that was to change a link in the Framework:
Now I see:
Now to see if it really works…
Java 8 Download Mac Os
**Update 1 **8/7/09: That link I created wasn’t quite right in the original post. It was creating a link with an absolute path. This apparently caused the Java Preferences app to fail to start and also caused WebKit/Safari to crash on all but the simplest web pages. Wierd. Corrected link creation above.
