Description
If I build Kepler using RELEASE-BRANCH-1-0-0 and ptII using rel-7-0-beta-2
from source using:
ant full-clean rebuild
and then run the Statistical Summary demo that uses R, I get:
java.lang.NullPointerException

Added a better error message. Also pointed the user to section 8.2.2 of the user manual that explains how to install R for kepler.
