Reproduce steps:

Deploy the attached EAR to Wildfly 8.

Problem:

Won't start because CDI scans all bean archives and stumbles across a public-Field in AbstractProcessEngineRestServiceImpl in engine-rest.

Expected behavior:

Works with CDI and embedded in an EAR.

Workaround:

Add to EAR - META-INF/jboss-all.xml with content:

<?xml version="1.0" encoding="UTF-8"?>
<jboss xmlns="urn:jboss:1.0">
<weld xmlns="urn:jboss:weld:1.0" require-bean-descriptor="true"/>
</jboss>

This disables implicit bean archive scanning and requires a beans.xml for each Bean archive to be valid.
