So is the issue that java.library.path isn't going to be set correctly 
when libraries are migrated to this new layout? Just wondering if the 
setup of the search path (in os::init_system_properties_values would be 
better place to do consider this). A concern with changing 
System.loadLibrary is that it has a wider impact.
