Gili commented on MJLINK-27:
----------------------------
Note that I did not include the JLink plugin in this testcase, because I've
never used it before. I would appreciate you updating the testcase to using the
jlink-maven-plugin now that you understand the expected behavior.
> Code incorrectly assumes that two modules won't have the same name

> Karl Heinz Marbaise closed MJLINK-7 referencing [a Stackoverflow

> 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.
