Title: issue with rake sunspot:solr:run failing with JRUBY 1.7.0.preview2

The upcomming jruby 1.7 release changes the behavior of Kernel#exec
which leads the rake task sunspot:solr:run to fail with message "Error:
Unable to access jarfile start.jar".
After replacing Kernel#exec with Kernel#system the rake task works
again.
