@retaildev you can see the changes that are being made to the Broadleaf framework at
https://github.com/BroadleafCommerce/Br ... e/pull/930. As you indicated, one of the harder things was to upgrade Jackson to the latest version with the change in maintainers.
As of right now, that branch is the 'spring4' branch of the framework, utilizing Broadleaf 3.2.0-SNAPSHOT. If you want, you could pull down the framework, switch to that branch, ensure that you are targeting Broadleaf 3.2.0-SNAPSHOT and try out Spring 4 in your project. We have not built any of the Broadleaf spring 4 artifacts onto our nexus. We would love to hear about any problems that you might run into so that we can get them resolved. At this point, that branch is relatively stable.
The one thing we are still discussing internally is exactly what version of Broadleaf will Spring 4 target. As I said, we are currently targeting Broadleaf 3.2.0-SNAPSHOT but that might change to a later version of Broadleaf. We should have that ironed out in the next couple of weeks.
