Not sure where to send this… Fired up Yosemite DP. Opened Terminal. Typed 'java' and was sent (via "More Info") to the OpenJDK download page. Downloaded JDK 8 Update 05. Mounted the image. Double-clicked the installer:
*Java from Oracle requires Mac OS X 10.7.3 or later.* Your system has Mac OS X Version 10.10. This product can be installed on Version 10.7.3 or later. Visit java.com/help for more information.
