@Resource injection of env-entry is not working in JBoss EAP 6

Issue

• We have a singleton startup EJB which is setup to initialize with an "env-entry" in ejb-jar.xml using @Resouce(name="name"). But this variable is not getting initialized and we are getting "null" as the value during runtime.

The ejb-jar-xml has:

        ...
        <session>
            <ejb-name>ExampleBean</ejb-name>
            <session-type>Singleton</session-type>
            <env-entry>
                <env-entry-name>example</env-entry-name>
                <env-entry-type>java.lang.String</env-entry-type>
                <env-entry-value>value</env-entry-value>
            </env-entry>
        </session>
        ...

The Singleton looks like:

@Startup
@Singleton
public class ExampleBean {
    @Resource (name = "example")
    private String example;
}
