I have a question to JBoss on who's responsible for processing the exclusions. If GF is responsible see
WeldBootstrap.parse() which is called by BeanDeploymentArchiveImpl.getBeansXml().
Need to add system property cdiTckExcludeDummy
Must add the following environment variable definition to domain.xml as a sub-element of <java-config>. Note that there are 2 locations in domain.xml for this.
