OS X 10.10 seems to prompt the user to install Java differently than previous versions of OS X. In my case I ended up with the JRE installed, which does not place Java at a directory like /usr/bin/java, but only installs the browser plug-in. This caused the old scripts to fail. So now we will call Java from the Internet Plug-Ins directory to be safe, since the JDK and JRE both install the plug-in.
