Hard to tell without seeing the whole code. I'd guess you have AbstractKernelTest somewhere in your hierarchy? Which installs a SecurityManager: | public static AbstractTestDelegate getDelegate(Class clazz) throws Exception | { | AbstractTestDelegate delegate = new AbstractTestDelegate(clazz); | delegate.enableSecurity = true; | return delegate; | } | The tests get only very basic privilieges, the idea being that we want to make sure the MC works properly in a restricted environment.
