CAS JDK version question

[Carl Waldbieser]

In the docs for CS 6.4 installation (https://apereo.github.io/cas/6.4.x/planning/Installation-Requirements.html) it reads:

CAS at its heart is a Java-based web application. Prior to deployment, you will need to have JDK 11 installed.

Is JDK 11 an exact requirement?  Or are later versions of the JDK also acceptable?  I don't follow Java development too closely, but I did see that JDK 17 is in general availability, so it just got me wondering.

Thanks,

Carl,

I believe 11 is a long term support version. It is what we use.

I have not tried more recent versions.

6.4, JDK 16:
https://apereo.github.io/cas/6.4.x/release_notes/RC3.html#jdk-16-compatibility

6.5, JDK 17:

Also 6.5 now passing builds for 18-ea.
