Hi,

It's an easy change to swap the test dependency from Closed- to Open Liberty. I incidentally just did the same the other day here: 

https://github.com/javaee-samples/microprofile1.2-samples/commit/a0abc87826f465e5a03202b175dd0afbbf13b790

But as removing is always easier I'd say go for it.

Kind regards,
Arjan
