I have a Weld SE application.
If I set the system property javax.enterprise.inject.scan.implicit to true and the system property org.jboss.weld.se.archive.isolation to false, the BeansXmlParser throws a NullPointerException when trying to merge the archives as no BeansXml instance is present on which the methods for the merge are called:
