What happened?

I am using the exact same image used by Microsoft for their hosted agents to run a self-hosted Ubuntu 22.04 agent (https://learn.microsoft.com/en-us/azure/devops/pipelines/agents/hosted?view=azure-devops&tabs=yaml and https://github.com/actions/runner-images/blob/main/images/ubuntu/Ubuntu2204-Readme.md) and JAVA_HOME environment variables are not appearing in the System capabilities.

The environment variables are part of the PATH (if that exists in Linux):

adminuser@vmss-agents-1:~/azdevopsagent$ $JAVA_HOME_17_X64
-bash: /usr/lib/jvm/temurin-17-jdk-amd64: Is a directory
adminuser@vmss-agents-1:~/azdevopsagent$ $JAVA_HOME_11_X64
-bash: /usr/lib/jvm/temurin-11-jdk-amd64: Is a directory
adminuser@vmss-agents-1:~/azdevopsagent$ $JAVA_HOME
-bash: /usr/lib/jvm/temurin-11-jdk-amd64: Is a directory

The agent installs Temurin JDKs and I think the agent is not supporting those.

Please see this for details: https://github.com/actions/runner-images/blob/main/images/ubuntu/scripts/build/install-java-tools.sh
