Apple released Java updates for Mountain Lion, Lion and Snow Leopard on Thursday that addressed security issues and also push users to Oracle's own Java plug-in for the Mac.
Apple distances itself from Java support with new update
According to Apple's notes for the Mountain Lion and Lion versions of the updater, "This update uninstalls the Apple-provided Java applet plug-in from all web browsers. To use applets on a web page, click on the region labeled 'missing plug-in' to go download the latest version of the Java applet plug-in form Oracle."
On Macs running Snow Leopard, the update leaves the Java plug-in in place but changes the default settings to prevent Java applets from running automatically.
Apple has been transitioning away from providing its own Java plug-in for the Mac, so it isn't any surprise that these updates are pushing users towards the Oracle-supported versions.
Java for OS X 2012-006 1.0 for Lion and Mountain Lion is available via Software Update, or as a downloadable installer at the Apple Support website. Java for Mac OS X 10.6 Update 11 is available through Software Update or the Apple Support website, too.
