> As seen in our Continuous Build environment on Jenkins (at Apache), but setup to use Java 7 (here: https://builds.apache.org/job/Pivot-trunk%20on%20Java%207/ ), any build of Pivot sources (from the trunk) now raise some compilation errors.
> Probably some has to be changes even in build.properties and build.xml to let our CI builds to force 1.7 as Java version (source an target) ... an idea could be to keep the release if specified in build.properties, otherwise use those in the current Java version.
> Some discussion here:
