You have to be running with a SecurityManager enabled to see this, which mean you need to have a valid security policy defined. The base test class that enables the SecurityManager should also be installing the test specific policy. I don't remember off the top of my head what this class is. The error you show means that the CodeSource for the current jboss-dependency.jar has not been granted the "java.lang.RuntimePermission getClassLoader" permission.
