Uninstall AdoptOpenJDK on Mac: Follow These Steps

The AdoptOpenJDK project is a community-driven, open-source contribution that offers OpenJDK's pre-built, free binaries of such reference versions of the Java programming language.

The aim of the AdoptOpenJDK group is to make certain that these Java downloads, which are kept up to date on a regular basis, are always accessible to everyone. However, because of the reoccurring bugs and errors that seem to be challenging to resolve, users would just uninstall AdoptOpenJDK on Mac instead.

As you proceed with the uninstallation, it is also possible to encounter problems if you don't know how to do the removal process. To know the other details to do so, follow this article.

Part 1. What is AdoptOpenJDK?

OpenJDK, which stands for "Open Java Development Kit," is an implementation of the Java Platform, Standard Edition (Java SE), that is both open-source and free. It is the end product of a project that Sun Microsystems started in the year 2006.

AdoptOpenJDK uses infrastructure, build and test scripts to produce prebuilt binaries from OpenJDK class libraries and a choice of either OpenJDK or Eclipse OpenJ9 VM. It means that AdoptOpenJDK is "binaries + installers" while OpenJDK is only the source code. So AdoptOpenJDK is not the same as the OpenJDK.

The program is granted a license under version 2 of the GNU GPL (General Public License), with the restriction that linking is permitted. Items that are connected to the Java class libraries might be subject to the rules of such GPL license if it weren't for an exemption to those restrictions that the GPL provides for linking. Since version 7, OpenJDK has served as the official reference model of Java Standard Edition.

This Project's objective is to develop a JDK 7 version for Mac that is of the highest possible quality and is open source.

Part 2. Manual Ways to Uninstall AdoptOpenJDK on Mac

Users need to have Administrator access and run the uninstall command either by utilizing the other removal tool or as root in order to successfully remove the JDK. If one does not have Administrator credentials, one can not uninstall the JDK.

When you install the JDK, the JRE will be installed too. And the JavaFX SDK and Runtime will also be integrated into the JDK directory structure.

• To use the Terminal to remove Java before you uninstall AdoptOpenJDK on Mac, follow the steps below:

1. Open Finder> Select the Utilities
2. Open the Terminal, in the window just copy and paste the following instructions:

sudo rm -fr /Library/Internet\ Plug-Ins/JavaAppletPlugin.plugin
sudo rm -fr /Library/PreferencePanes/JavaControlPanel.prefPane
sudo rm -fr ~/Library/Application\ Support/Oracle/Java

• If you used HomeBrew to install the JDK app before, you can also uninstall AdoptOpenJDK on Mac using the commands such as:

brew uninstall openjdk8 or brew uninstall adoptopenjdk8

• To delete the folder whose filename follows the following format:

1. Go to users/Library/Java/JavaVirtualMachines
2. Delete the file or directory minor.macro[_update].jdk.
3. You can use the command sudo rm -fr JavaVirtualMachines/*

• You should determine which JDK version is installed on your Mac because there can be different JDKs in a system:

1. Type java -version in the Terminal.
2. Then you will see the information. If you can see the text 8.0_06, for example, from the strings, then the version is 8u6
3. To remove 8u6, use the command: % rm -rf jdk1.8.0_06.jdk

Note: It is not recommended that you try to remove Java by deleting the Java utilities from the/usr/bin directory. Because this folder is a component of the operating system software, any modifications that you make to it will be discarded with Apple the very next time you update the operating system.
