Sure, I can create and maintain metapackage. (In this case it would

If you really think that old JDK should be removed during update and
insist on that then there is still a way to achieve that with versioned
obsoletes. Metapackage would Obsolete: java-1.N.0-openjdk* < e:v-(r+1),
where e:v-r is the latest evr of java-1.N.0-openjdk* when JDK N was
considered as "main JDK". I've just tested it and it works, see below.
Lets start with JDK 7 installed.
sh-4.3# rpm -qa | grep java
java-1.7.0-1.fc23.x86_64
java-1.7.0-openjdk-1.7.0-1.fc23.x86_64
Update installs JDK 8 and erases JDK 7.
sh-4.3# dnf -y update

Nothing to do.

After update only JDK 8 is installed:

java-1.8.0-1.fc23.x86_64

sh-4.3# dnf install -y java-1.7.0-openjdk

JDK 7 and 8 can coexist without any problem:

java-1.8.0-openjdk-1.8.0-1.fc23.x86_64
java-1.7.0-openjdk-1.7.0-2.fc23.x86_64
