I suspect this is an older JDK brought over from the Yosemite install and the consensus on the Internet I could find suggest to leave that alone as the system needs those.Īpparently in older versions of OS X it was possible to run /usr/libexec/java_home -uninstall to get rid of a Java install, but that option does not appear to work in OS X Sierra anymore.
Easy to follow details about how to install OpenJDK are available here.
As I’m writing this, Java 11.0.9 is the latest LTS (Long Term Support) version and AdoptOpenJDK is one of the best places to find Prebuilt OpenJDK Binaries. For some reason, I had ended up with both 1.8.0_60 and 1.8.0_131 installed on my machine, and Oracle’s uninstall instructions didn’t touch the 1.8.0_60 install in /System/Library/Frameworks/amework. Since OS X 10.7 Java is not (pre-)installed anymore, let’s fix that. Unfortunately in my case this didn’t end up uninstalling an older version of the JDK. It’s a rather manual approach but at least it is documented and the whole procedure consists of three commands. Removing the existing installationįortunately Oracle has uninstall instructions on their website. Oh, and installs the same JDK anyway, just without all the additional pointy clicky work.

It’s just so much easier to get updates and update information all in one place. 1) brew cask install java 2) java -version java version '' Java(TM) SE Runtime Environment (build -b11) P.S - Cask is an extension to Homebrew that is intended to manage large Mac binaries and graphical applications, but using the Homebrew interface. As I move the management of more development tools from manual management over to homebrew, I decided to use homebrew to manage my Java installation also. It was the typical “download from the Oracle website, then manually run the installer” deployment. I’ve had a ‘manual’ install of JDK 8 on my Mac for quite a while, mainly to run Clojure.
If you want to install a specific major version of the JDK (6 or 8 at the time of writing), I describe how to do that in this new blog post. _ Update: The title of this post isn’t quite correct as using the homebrew cask mentioned in this blog post will install the current major version of the Oracle JDK. The installation method described below will still work as it uses the non-versioned java cask, which installs the latest version of OpenJDK. Check that the installation works: java -version openjdk version OpenJDK Runtime Environment (build -b08) OpenJDK 64-Bit Server VM (build 25. Update II - : It looks like due to the recent licensing changes, the Java 8 JDK that brew used is not directly accessible anymore and likely behind some kind of paywall. Run the yum command, specifying the package you want to install: sudo yum install java-1.8.0-openjdk.
