Description of problem:

An upgrade of jboss-modules to 1.3.1.Final makes a regression in org.jboss.osgi.framework.spi.BundleReferenceClassLoader, see the stacktrace from org.jboss.as.osgi.launcer.FrameworkFactoryTestCase below. 

JBOSGI-762 is needed to fix this.


Version-Release number of selected component (if applicable):

org.jboss.osgi.framework:jbosgi-framework-core:2.1.0.Final
