is there a specific conflict or problem (or a huge chain of dependencies) ?
To me it seems the answer to both is no -
This is the requirement list -
java >= 1.5 jpackage-utils rpmlib(CompressedFileNames) <= 3.0.4-1 rpmlib(FileDigests) <= 4.6.0-1 rpmlib(PayloadFilesHavePrefix) <= 4.0-1 rpmlib(PayloadIsXz) <= 5.2-1
Probably a matter of packaging?
IIRC, Alon was the one who replied, and the issue was that Jboss included an old version (and we don't have classpath isolation, I guess)
Greg
We would like to avoid maintaining and package components that are not provider either by el6 or jboss distribution.
But based on other threads, it seems that I am the only one who remained trying to push compliance to the old ways, people feel that can maintain anything anywhere with no effort.
Regards, Alon
Alon, I disagree with your comment (about the "you're the only one" part :) ) As I wrote - I had a strong deja-vu about that the issue was already brought up. Now that you reminded , I don't think you're the only person who feels this way. I would also like to understand more what it means before jumping to conclusions and upgrading to collections4. At past I had some issues with another commons project (commons-configuration) that had different versions upstream and downstream. I am sure the changes include not just "move to generics" and should carefully be considered.
If I may clarify, there would be at least two stipulations for introducing collections4.
1. someone else packages it and maintains it, available in Fedora and EL, long term. Quality package.
this is what missing, us maintaining a new package just to have more beautiful code is something that can be deferred for now.
2. JBoss has proper classloader isolation so that, even though JBoss uses collections3, a webapp can use collections4.
should not be a problem to use both.
I don't know the answer to either question :)
Seems like minimal gain to me, though.
