If I read this correctly then it will prepend \\?\ which is consistent 
with what we do in other areas of the platform when presented with a 
long file name. Have you looked at moving open_jarfile to a platform 
specific source file?, in this case it might be better if the WIndows 
specific code were in src/java.base/windows/native/libjli for example.
