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
(for example message-ID 54ECA102.1070506@xxxxxxxxxx)
Yah. Sorry. I walked across it later then replied this.
However - I'm not convinced that metapackage will work as expected. If
Still the metapackge's correct dependence have to be someones responsibility. Will you be able to

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

update, but that's expected behaviour of package management software,
such as DNF, and JDK packages should not differ from other Fedora
Really should not? We done pretty god work to have only one main jdk unlike python1, python2,python3
or glib2,glib3,glibN... We are settled in special directory and so on. So in what is JDK actually
similar to other packages?
packages in this aspect. Consider a detailed example below.
Thank you for this. I understood it from yuor describtion and already had the same. However I
consider the keeping of old jdk as no-go for this.

Assume we start with Java 7:
sh-4.3# rpm -qa | grep java
java-1.7.0-openjdk-1.7.0-1.fc23.x86_64
java-1.7.0-1.fc23.x86_64
Then update to newer version of java metapackage, which brings Java 8:
sh-4.3# dnf -y update

Now both Java 8 and legacy Java 7 are installed:
sh-4.3# rpm -qa | grep java

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