I read a few posts and followed their suggestion of updating JAVA to the latest version 8 update 20, and JRE version 8 update 71, to no avail. Any anyone shed some light on this please?

I addition to updating Java to latest version, I had to also set a correct path for JAVA_HOME environment variable.

In my case I edited ~/.bash_profile and added:

export JAVA_HOME=/usr/lib/jvm/jre-1.8.0-openjdk.i386/

Make sure the path matches the Java version you're running.

  • `/usr/libexec/java_home` to find the home path, and `brew cask install java` to install latest java – Dorian Jun 30 '18 at 18:57
