Source is:

@Resource
public void setSessionContext(SessionContext sc) {
sctx = sc;
}

jboss-metadata populates ResourceEnvironmentReferenceMetaData properly, given that there's no mapped-name.

However, EJB3 Module in AS has error:

java.lang.RuntimeException: mapped-name is required for sessionContext of deployment someEjbTest
at org.jboss.ejb3.client.ClientResourceHandler.loadXmlResourceEnvRefs(ClientResourceHandler.java:181)

This is a regression; was some code removed which populates mapped-name, given that the injection target is javax.ejb.SessionContext?
