Hi,
since few days we are having a proble with Arquillian and Java 8 which
breaks CI on master branch. I also started to have a similar problem
since we created the new master branch based on Java 8. Unfortunately
I'm not familiar with the JBoss stack, so I don't have a deep knowledge
of Arquillian. However I've found a blog post (in German
http://heckenmann.de/arquillian-und-wildfly/) with a repository that
helped me solving this problem with Arquillian. The only problem I still
have with this solution is that I can't run Arquillian test from IDE
(Eclipse in my case). In any case I hope that my work could help to
solve this problem. I committed pom changes here on GitHub:
