Deployment fails when Dependencies is empty in a jars manifest

I have a WAR, which produces the following error on deployment:
Caused by: java.lang.IllegalArgumentException: Empty module specification
at org.jboss.modules.ModuleIdentifier.fromString(ModuleIdentifier.java:169) [jboss-modules.jar:1.1.1.GA]
at org.jboss.as.server.deployment.module.ManifestDependencyProcessor.deploy(ManifestDependencyProcessor.java:83) [jboss-as-server-7.1.1.Final.jar:7.1.1.Final]
at org.jboss.as.server.deployment.DeploymentUnitPhaseService.start(DeploymentUnitPhaseService.java:113) [jboss-as-server-7.1.1.Final.jar:7.1.1.Final]
... 5 more

I found that my WAR contains a jar in WEB-INF/lib that has empty dependencies defined in its manifest. More exactly it's "Dependencies: ", so the colon is followed by a space character before the new line characters. The ManifestDependencyProcessor parses this as one dependency, the name of which is the empty string.
