Revision 72296:
http://fisheye.jboss.org/browse/JBossAS/trunk/ejb3/src/main/org/jboss/ejb3/deployers/Ejb3Deployer.java?r1=71162&r2=72296

...has made the change that a null scope is passed into the ctor of Ejb3JBoss5Deployment, causing an NPE later down the chain:

Caused by: java.lang.NullPointerException
at org.jboss.ejb3.deployers.JBoss5DeploymentScope.getEjbContainer(JBoss5DeploymentScope.java:155)
at org.jboss.ejb3.Ejb3Deployment.getEjbContainer(Ejb3Deployment.java:388)
at org.jboss.ejb3.EJBContainer.resolveEjbContainer(EJBContainer.java:1320)
...etc

I'd tried setting:

scope = new JBoss5DeploymentScope(unit);

...in the case that parent==null, but this leads to deployment errors of other services on Startup. Additionally,

unit.getAttachment(DeploymentScope.class)

...returns null.

To test, run the "service" integration tests from the EJB3 TestSuite.
