    Description

      https://github.com/wildfly/wildfly-core/blob/5.0.0.Alpha7/server/src/main/java/org/jboss/as/server/moduleservice/ExtensionIndexService.java#L94 reads extensions from jars manifest like:

      File jar = new File(<jar>)
      final JarFile jarFile = new JarFile(jar);
      final Manifest manifest = jarFile.getManifest();
      final Attributes mainAttributes = manifest.getMainAttributes();
      ...
      

      The latest IBM jdk 8.0-5.11 (and possible some of previous releases) contains some jars [1] where manifest.getMainAttributes(); throws NPE, causing deploy operation of archive with Extension-List to fail, see WFLY-10349.
