      As per request attached to comment on changes needed to OS X installer.

      When running from the command line (as opposed to instantiating a JVM programmatically), Java 7 or Java 8 on OS X has a dependency on the very old Java 6 installation for OS X, available at http://support.apple.com/kb/DL1572. When the user installs the Java 6 package from Apple, /usr/bin/java points to the Java 6 installation. Oracle Java installs into /Library/Internet Plug-Ins/JavaAppletPlugin.plugin/Contents/Home. To run a Java 8 JVM from the command line, the user needs to give the full path to the "java" executable – /Library/Internet Plug-Ins/JavaAppletPlugin.plugin/Contents/Home/bin/java.

      The quick fix is to change the /Library/Application Support/Jenkins/jenkins-runner.sh file with the following unified diff:
