JAX-WS handler chain file inside EJB-Jar not recognized while using WAR packaging (AS7.1.0.CR1)

[r.reimann]

I've got an EJB-Jar module with an EJB3 stateless session bean as JAX-WS endpoint. The endpoint references a handler chain via @HandlerChain annotation. While deploying the WAR the following exception is thrown.

12:50:09,379 ERROR [org.jboss.msc.service.fail] (MSC service thread 1-16) MSC00001: Failed to start service jboss.deployment.unit."jaxws-injection-ejb3.war".PARSE: org.jboss.msc.service.StartException in service jboss.deployment.unit."jaxws-injection-ejb3.war".PARSE: Failed to process phase PARSE of deployment "jaxws-injection-ejb3.war"

As far as i can tell from looking at the corresponding AS7 code the exception means that the handler chain file wasn't found. I could reproduce the issue by adding the code below to the existing AS7 integration test:

https://github.com/jbossas/jboss-as/blob/master/testsuite/integration/basic/src/test/java/org/jboss/as/test/integration/ws/injection/ejb/basic/InjectionTestCase.java

and deploying the exported jaxws-injection-ejb3.war against nightly build #402.

        WebArchive ejb3War = ShrinkWrap.create(WebArchive.class, "jaxws-injection-ejb3.war");
        ejb3War.addAsLibraries(sharedJar);
        ejb3War.addAsLibraries(ejb3Jar);
        java.io.File tempDirectory = new java.io.File("/Users/rr/Downloads/_tmp");
        ejb3War.as(org.jboss.shrinkwrap.api.exporter.ZipExporter.class).exportTo(new java.io.File(tempDirectory, ejb3War.getName()), true);
        System.out.println(ejb3War.toString(true));

I'm not sure if this is a bug or if the kind of packaging i'm trying is not yet covered by the current specs since as far as i remember JAX-WS predated JavaEE6 which introduced the possibility to package EJB-Jars inside a WAR.
