The value of the xmln in ejb-jar.xml is not correct.

The xmlns has to be "http://xmlns.jcp.org/xml/ns/javaee", not "http://xmlns.jcp.org/xml/ns/javaee/" according to the schema.
Test:
org.jboss.cdi.tck.tests.context.passivating.enterprise.invalid.StatefulSessionBeanXmlDescriptorTest

@1.1.0.SP1:
<ejb-jar version="3.2" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns="http://xmlns.jcp.org/xml/ns/javaee/">

Should be:
<ejb-jar version="3.2" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns="http://xmlns.jcp.org/xml/ns/javaee">
