Here's a small article to identify the Java version being used inside vRO or vRA 8.x
As a first step one has to identify container id
Let's first grep for VCO processes
docker ps | grep vcoThe output of above command would be as follows
root@premvra [ ~ ]# docker ps | grep vco

We need to fetch container id from the above output one we want to know the java version
Since we are interested in vco-server-app and this has an id: d572660d055c from the above
Then use the following command to find out the java version
root@premvra [ ~ ]# docker exec -it d572660d055c java -version
openjdk version "1.8.0-internal"
OpenJDK Runtime Environment (build 1.8.0-internal-_2019_10_29_05_18-b00)
OpenJDK 64-Bit Server VM (build 25.71-b00, mixed mode)
We can also check from vco-app-server logs under /var/log/container/ which will ve logged during service startup.
