The system module library is special and needs to be created in a way 
that takes account that it part of an image. For compatibility (and 
usability reasons) this means that the commands (javac, java, etc.) need 
to be in the image's bin directory rather than a module-private 
location. Native libraries are complicated by dependencies and also the 
need to have libjvm in a known location so that custom launchers can 
dlopen it. So yes, definitely not functional if you do the above. In any 
case, I think the VM has to special case the base module and has to have 
code to detect that it's running with module image.
