Removing Java Runtime from OS X

Java 8 removes the Medium Security

Removing Java From OS X


Since Java 8 came out you no longer have the ability to run self signed java runtimes.  This is a good thing from a security perspective but some devices like iKVM's use java self signed certificates to allow access and if your running Java 8 and OS X you might have a problem.  My solution to this was to uninstall java 8 using the following commands

sudo rm -rf /Library/Java/JavaVirtualMachines/jdk{version}.jdk

sudo rm -rf /Library/PreferencePanes/JavaControlPanel.prefPane

sudo rm -rf /Library/Internet\ Plug-Ins/JavaAppletPlugin.plugin

Then I installed the latest version of Java 7 which will only be available until April 2015, but it will still be made available though the Java Archive.
