With the fix for RT-19880 we moved the following utility jar files from the tools directory to the lib directory in the SDK:

    ant-javafx.jar
    javafx-doclet.jar
    javafx-mx.jar

Starting with NB 7.1.2 will look for the ant-javafx.jar file first in the new "lib" directory, and then as a fallback, in the old "tools" directory. This is being tracked by NetBeans bug http://netbeans.org/bugzilla/show_bug.cgi?id=208798

This will require us to modify the build files in the apps repo, and regenerate the nbproject files once a NB 7.1.2 build is available with this fix.
