Unit tests fail (Portugese)

For (for a while I think) the unit tests (for standalone project) were failing for me in Portugese:

I am running on Linux with JDK 17 and just pulled the latest sources in ‘master’ branch

I’ve just pulled the latest code and the [pt] unit tests still fail for me. I’ve also tried jdk8 with the same result.
Interestingly enough, they do pass in Eclipse.
