WIP commit [1] demonstrates failures affecting tests execution for the `intergation/microprofile-tck/metrics` module.

We're currently looking into those failures but we noticed that adding the `module.path` system property to the `surefire` plugin configuration would fix them [2].
That property should not be taken into account by the bootable JAR Maven plugin ant the modules in that path should not belong to the bootable JAR as well.
