Java version in 2021.09

[pitc]

How can I tell the version of Java installed and its source?
For 2021.09.3703 is there a place to find out if the Java version is OpenJdk or Oracle?

Update: if I examine the admin page on a tomcat server it will show me the java version.
Is this the one that both Tomcat and the application use?
I will assume it is.

The application server is running inside a container on the Tomcat server, so yes the application server will run on the same Java version.
However, you can check this as well by opening the Servoy Admin page of your application server

you mean if you open the admin page of a developer?
that is the same yes

in a developer you can also get it through the menu-> Help -> About Servoy developer -> Installation details-> Configuration

and there you can find system properties like: java.version=Version_of_Java
