Affects: Release Notes
Help Desk Ticket Reference: https://c.na7.visual.force.com/apex/Case_View?sbstr=00769055
Steps to Reproduce: 1. Extract the attached HelloService-EAP6-inject-reproducer.tar.gz
2. modify "jboss.home" and "jboss.server.config" in build.properties to suit your environment
3. execute "ant jar" to create HelloService.sar archive
4. execute "ant deploy" to deploy the sar archive to JBoss 

Workaround Description: Define the POJO as a MBean then inject it via MBean Object name like {{<inject bean="example:type=HelloService,service=myTask"/>}} instead of {{<inject bean="myTask"/>}}. See the attached HelloService-EAP6-inject-workaround.tar.gz.
project_key: JBPAPP6

The following injecting POJO to MBean by using {{<inject bean="myTask"/>}} in {{jboss-service.xml}} of SAR works fine in EAP 5:

* META-INF/jboss-service.xml:

{code:xml}
<server>
  <mbean code="com.redhat.jboss.support.HelloService"
         name="example:type=HelloService,service=Hello">
     <attribute name="Message">Hello!!</attribute>
     <attribute name="Task"><inject bean="myTask"/></attribute>
  </mbean>
</server>
{code}

* META-INF/jboss-beans.xml:

{code:xml}
<?xml version="1.0" encoding="UTF-8"?>
<deployment ... >
  <bean name="myTask" class="com.redhat.jboss.support.SimpleTask">
  </bean>
</deployment>
{code}

But the same way does not work in EAP 6 with the following ERROR at deployment of SAR:
