Hi Calvin,

Some clarifying questions.  Is this just an issue for exploded builds?  
I would prefer the exit to occur if the os::stat() fails for the system 
class path in os::set_boot_path().  With certainly an added assert later 
in ClassLoader::setup_bootstrap_search_path() to ensure that the system 
class path is never NULL.
