The org.wildfly:wildfly-ts-integ parent POM has a property ts.microprofile-tck-provisioning.fp.artifactId to manage the feature pack for when provisioning a test server. The bootablejar.preview.profile profile, -Dts.bootable.preview, does not override this property. This means that for the MicroProfile TCK's when the profile is used, the bootable JAR is not provisioned with the correct feature pack.
