Warning: class_loader.impl: SEVERE WARNING!!! A namespace collision has occured with plugin factory for class stag_ros::StagNodelet. New factory will OVERWRITE existing one. This situation occurs when libraries containing plugins are directly linked against an executable (the one running right now generating this message). Please separate plugins out into their own library or just don't link against the library and use either class_loader::ClassLoader/MultiLibraryClassLoader to open.
