There is no environment variable for JAVA_HOME in the docker image for xl-release:20.0.1
It used to be in the image for xl-release:10.0.3 which I used before upgrading.
We would appreciate the environment variable is set in your image as we build on top of your image.
In the previous versions, the environment variable(JAVA_HOME) came from the underlying base image and was not specified by Digital.ai.
If you need it, we recommend you add the env_var to your own Docker file.
