iwlax2xx-firmware package in OL8, are in fact, available in the iwl7260-firmware package in RHEL, thus, we are

The java-1.7.0-openjdk package expects that the /var/lib/rpm-state/ directory is present. Yet, it may be missing.
This directory is supposed to be created by the copy-jdk-configs package during the system installation, but it does
not do that: https://bugzilla.redhat.com/show_bug.cgi?id=1620053#c14.
If the original system has an older version of copy-jdk-configs installed than the one available in RHEL repos, the
issue does not occur because the copy-jdk-configs is updated together with the java-1.7.0-openjdk package and a
pretrans script of the copy-jdk-configs creates the dir.
In case there's no newer version of copy-jdk-configs available in RHEL but a newer version of java-1.7.0-openjdk is
