I recently downgraded my java version from
java-1.11.0-openjdk-amd64
to
java-1.8.0-openjdk-amd64
At the moment I have
user-admin@V0007054:~$ java -version
openjdk version "1.8.0_181"
OpenJDK Runtime Environment (build 1.8.0_181-8u181-b13-1ubuntu0.18.04.1-b13)
OpenJDK 64-Bit Server VM (build 25.181-b13, mixed mode)
Since then almost all my apps including IntelliJ,Rubymine and Slack stopped working. I'm convinced that this happened after the downgrade. I uninstalled IntelliJ and reinstalled it (twice) through Ubuntu Software app again, but it still doesn't come up when I click on the app.
I did google it for a while but couldn't find any useful info about this. Any help is much appreciated.
