MacOS X remove Java 9

macosx_remove_java9.sh

sudo rm -fr /Library/Java/JavaVirtualMachines/jdk-9.jdk/
sudo rm -fr /Library/Internet\ Plug-Ins/JavaAppletPlugin.plugin
sudo rm -fr /Library/PreferencePanes/JavaControlPanel.prefPane

To disable it, you can rename the Info.plist to Info.plist.disabled in /Library/Java/JavaVirtualMachines/jdk-9.0.1.jdk/Contents/
It then stops listing under /usr/libexec/java_home

thanks!!

thanks a lot.

Regards.

Thanks rahulsh1! That's neat.

Thanks! I needed to delete the whole Java folder to get rid of JDK 9... but... that's life :D

Thanks. This helped.

Thanks!

Save me a lot of time.

woo hoo! thanks! very helpful!

i found a simplest way.

for macOS high sierra removing java 9:

delete the java folder you find in the dir shown to you after executing:

/usr/libexec/java_home -V

use "Go to" in finder and copy and paste the dir to get there

My hero.

$ sudo rm -fr /Library/Java/JavaVirtualMachines/jdk-9*.jdk/
$ sudo rm -fr /Library/Internet\ Plug-Ins/JavaAppletPlugin.plugin
$ sudo rm -fr /Library/PreferencePanes/JavaControlPanel.prefPane

$ /usr/libexec/java_home -V
Unable to find any JVMs matching version "(null)".
Matching Java Virtual Machines (0):
Default Java Virtual Machines (0):
No Java runtime present, try --request to install

On Mac Terminal
echo $JAVA_HOME

on bash_profile place the below line with your required version
export JAVA_HOME=/Library/Java/JavaVirtualMachines/jdk1.8.0_{ should be your version }.jdk/Contents/Home
export $PATH=$JAVA_HOME/bin:$PATH

Cheers, this saved me a hassle of reverting back to an older Java version.

I ended up installing java via homebrew brew tap caskroom/versions then brew cask install java8 more here https://www.lonecpluspluscoder.com/2017/10/08/installing-other-versions-of-the-java-jdk-via-homebrew/ and adding it to JAVA_HOME similar to others here.

Works like a charm!

Many Thanks!!!
