May you be more exact with the metapackage? Before I come up with
legacy, I hoped to solve the issues via some metapackage. At the end I
gave up, because the touch of user was always necessary.
I described it in much detail in other posts in this thread

Yah. Sorry. I walked across it later then replied this.

Sure, I can create and maintain metapackage. (In this case it would
probably be subpackage of javapackages-tools.)

It works exactly how I described it. Old JDK won't be removed during

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.

JDK 7 and 8 can coexist without any problem:
sh-4.3# rpm -qa | grep java
java-1.8.0-openjdk-1.8.0-1.fc23.x86_64
java-1.7.0-openjdk-1.7.0-2.fc23.x86_64
java-1.8.0-1.fc23.x86_64
I very much like this approach!
Even with the whole complexity?
