Right now there's a few workarounds in the setup of OpenSocial due to conflicts in versions:

1.) Shindig 2.0.x requires ehcache 2.2.0 - we have to run with version 1.5.0 as required by Magnolia, as the newer one is not backwords compatible.

2.) OpenSocial requires a newer version of nekohtml but we can't exclude the old one contained in Daisydiff right now. Workaround here is to add an explicit dependency to the desired version in the webapp's pom.
