Gili updated MJLINK-27:
-----------------------
    Description: 
Karl Heinz Marbaise closed MJLINK-7 referencing [a Stackoverflow 
post|https://stackoverflow.com/questions/46573572/java-9-possible-to-have-2-modules-with-same-name-on-module-path/46574200#46574200]
 to prove that module names must be unique. In fact, this Stackoverflow post 
says the exact opposite. The bottom half of the post states that modules in 
separate directories **are** allowed to have the same name. The bottom of the 
post concludes:
{quote}That makes it possible to have the same module in different directories.
{quote}
It doesn't have to be the same module per-se. It is possible for two different 
implementations with the same module name to reside on the module path, so long 
as the modules reside in different directory. This is useful for "class 
shadowing". In my particular case, I ship a no-op implementation of a module by 
default but users can insert a working implementation in front of the module 
path to enable the feature.

Please reopen this issue or continue its work here.
