rtt_actionlib::RTTSimpleActionServer::shutdown() method does not compile.

I think the idea was to use internally actionlib::SimpleActionServer<...>::shutdown(), but the inherited actionlib::ActionServerBase<...>::shutdown() simply does not exist. I get:

rtt_ros_integration/rtt_actionlib/include/rtt_actionlib/rtt_simple_action_server.h:70:4: error: ‘class rtt_actionlib::RTTActionServer<MyAction_<std::allocator<void> > >’ has no member named ‘shutdown’
