I've had a look | public void testURLChildOfGlobalUcl() throws Exception | { | L globalLoader = testScenario.createLoader(new CLDeploymentBuilder("GLOBAL", JAR_A_1)); | L childALoader = createChildURLLoader(globalLoader, JAR_B_1); | | testScenario.loadClass(childALoader, globalLoader, CLASS_A); | testScenario.loadClass(childALoader, CLASS_B); | | L childBLoader = createChildURLLoader(globalLoader, JAR_A_2); | System.out.println("========> G" + globalLoader); | System.out.println("========> A " + childALoader); | System.out.println("========> B " + childBLoader); | testScenario.loadClass(childBLoader, globalLoader, CLASS_A); | } | The output shows G and A to always have a classloader, probably because the testScenario call maintains a strong reference to the loader? B sometimes is shown to have null loader, so createChildURLLoader needs to be reworked somehow to maintain a strong reference to the loader.
