Answer 1

They usually reside in /usr/lib/jvm. You can list them via ll /usr/lib/jvm. The value you need to enter in the field JAVA_HOME in jenkins is /usr/lib/jvm/java-1.8.0-openjdk.

Update

when I look at '/usr/lib/jvm' I get ...

What you see there is a list of symbolic links pointing to a similar target located in /etc/alternatives. In the end they all point to the same target. The difference is only the name which allows you to choose how explicit your choice if the target version shall be.

(Because java-1.8.0-openjdk is missing: Maybe you also need to install the package java-1.8.0-openjdk-devel.)
