The idea behind this "-legacy" suffix was to ensure a reasonable upgrade
path for people *only* using default java-x.y.z-openjdk package.
Consider the following scenario (all hypothetical, not saying that any
Fedora releases and JDK releases align in this way):
F22 has default JDK of java-1.8.0-openjdk. Then, F23 will get
java-1.9.0-openjdk as default and F24 java-1.10.0-openjdk as default.
The upgrade from F22 => F23 will install java-1.9.0-openjdk and remove
java-1.8.0-openjdk. Similarly, the upgrade from F23 to F24 will install
java-1.10.0-openjdk and remove java-1.9.0-openjdk. This is to ensure
that no old JDKs stick around on the majority of Fedora systems.
If the name was kept there does not seem to be a good way to:
1.) Ensure dist upgrades update JDK packages
2.) Ensure dist upgrades remove old JDK package (which may no longer
get security updates).
Do you see a way to achieve this without a name change of the package?
