The issue is that you are trying to retrieve the classloader while running in a non-privileged block. | 2576 ERROR [AbstractKernelController] Error installing to Configured: name=PropHolder state=Instantiated | java.security.AccessControlException: access denied (java.lang.RuntimePermission getClassLoader) | at java.security.AccessControlContext.checkPermission(AccessControlContext.java:264) | at java.security.AccessController.checkPermission(AccessController.java:427) | at java.lang.SecurityManager.checkPermission(SecurityManager.java:532) | at org.jboss.kernel.plugins.dependency.AbstractKernelControllerContext.getClassLoader(AbstractKernelControllerContext.java:244) | at org.jboss.kernel.plugins.dispatch.InvokeDispatchHelper.invoke(InvokeDispatchHelper.java:76) | at org.jboss.beans.metadata.plugins.AbstractValueFactoryMetaData.getValue(AbstractValueFactoryMetaData.java:323) | at org.jboss.kernel.plugins.dependency.PropertyDispatchWrapper.execute(PropertyDispatchWrapper.java:82) | at org.jboss.kernel.plugins.dependency.PropertyDispatchWrapper$1.run(PropertyDispatchWrapper.java:96) | at java.security.AccessController.doPrivileged(Native Method) | at org.jboss.kernel.plugins.dependency.ExecutionWrapper.execute(ExecutionWrapper.java:52) | The ExecutionWrapper has switched back to the access control context of the person that registered the bean, i.e. the test. Which doesn't have the rights to get the classloader. The InvokeDispatchHelper needs to get the classloader from the context in a privileged block.
