When the structure deployers parse a top-level jboss-test-entity.jar with a manifest like:

Manifest-Version: 1.0
Ant-Version: Apache Ant 1.6.5
Created-By: 1.5.0_09-b01 (Sun Microsystems Inc.)
Class-Path: ejb.jar jnp-client.jar jboss-client.jar jndi.jar jboss-jmx
.jar junit.jar deploy.jar

it fails with:

Caused by: java.lang.IllegalStateException: JarHandler@28271403[path= context=file:/C:/home/svn/JBossHead/jboss-head/testsuite/output/lib/jboss-test-entity.jar
real=file:/C:/home/svn/JBossHead/jboss-head/testsuite/output/lib/jboss-test-entity.jar] has no parent.

The invalid references should at most produce debug level warnings.
