Oracle JDK rpms don't contain the list of required packages. This is by intention as Oracle JDK rpms are supposed to be installed on different Linux distributes and names of packages vary.

It would be good to let users know the list of packages required for all features of JDK.

For Oracle Linux 7 the list of required packages is:

jdk8
