Thanks everyone for your thoughts.
I would like to sum things up (as I understood from this thread) -
a. We will defer the move to commons collections4.
b. We should introduce some class renaming, not have LinqXXX
I think those renaming and general refactoring of compat should be a
series of bugzilla's we should communicate as
entry-level,low-hanging-fruits,you-name-it
for new comers to ovirt.
c. Later on we can shift to an "already maintained"
package.
I wonder how close we are to moving to java8 where all these
dependencies (commonsX, LinqWhatever) could go to the waste bin.
probably a mix of jboss/rhel/gwt.
