I'm upgrading from JBossAS 6 to 7CR1. The following code fragment was working before, but now I'm getting the stacktrace below.

Codefragment:
EnterpriseArchive ear = ...
JavaArchive ejbJar = ...
ear.addAsModule(ejbJar)
.addAsLibrary(
DependencyResolvers.use(MavenDependencyResolver.class)
.artifact("org.dbunit:dbunit:2.4.8")
.resolveAs(JavaArchive.class)
.iterator()
.next());

Stacktrace:
