Hello,

I have a customer using Ignition 8.1.  
Oracle Java SE 8 JRE is installed on the system. However, the customer does not want to use Oracle Java SE 8 JRE.

Can we uninstall Oracle Java SE 8 JRE and install Open JDK instead and run Ignition 8.1?

Thank you.

Ignition comes with its own Java runtime, and if you're current it's a version of JDK 17.

You do not need Oracle or any other Java 8 installed.

It's also not an Oracle build of the JDK, for what it's worth.
