I agree with Reindl here, if I understand him correctly. It would
certainly break upgrades in an unexpected way if an upgrade from
"java-1.7.0-openjdk" suddenly stopped carrying the graphical components.
Note -- I think that the way the feature has things constructed would
achieve something similar. The java package is essentially java-x11. It
would Require: java-headless.
So yum install java will get you the java w/X11 support.
[...]
I think it would be wise to do the same for Java. Create
'java-openjdk-1.7.0-headless' and 'java-openjdk-1.7.0--x11' and then
have the 'java-openjdk-1.7.0' metapackage install both of them.
I can see one advantage to this approach: it lets us tell packagers that
Requires: java should no longer be used. Packagers should determine whether
they're using APIs that require X and either Requires: java-x11 or Requires:
java-headless based on what they really need. We can then audit the
packageset at a later date to determine which packages haven't adjusted
their Requirements yet.
