  <p>On my Mac, Preferences > Java, Java tab, I see Platform 1.8, Product 1.8.0_121, and a path of 1.8   1.8.0_121   <a href="http://java.sun.com/products/autodl/j2se" rel="nofollow noreferrer">http://java.sun.com/products/autodl/j2se</a>    /Library/Internet Plug-Ins/JavaAppletPlugin.plugin/Contents/Home/bin/java</p>
