### Question:
ProxyModuleDefinition implements ModuleDefinition { public URI[] getLocations() { List<URI> uris = new ArrayList<URI>(); if (classLoader instanceof URLClassLoader) { URLClassLoader urlCL = (URLClassLoader) classLoader; for (URL url : urlCL.getURLs()) { try { uris.add(url.toURI()); } catch (URISyntaxException e) { Logger.getAnonymousLogger().log(Level.SEVERE, e.getMessage(), e); } } } else { String cp = System.getProperty("java.class.path"); if (ok(cp)) { String[] paths = cp.split(System.getProperty("path.separator")); if (ok(paths)) { for (int i = 0; i < paths.length; i++) { uris.add(new File(paths[i]).toURI()); } } } } return uris.toArray(new URI[uris.size()]); } ProxyModuleDefinition(ClassLoader classLoader);  ProxyModuleDefinition(ClassLoader classLoader,
      List<ManifestProxy.SeparatorMappings> mappings); String getName(); String[] getPublicInterfaces(); ModuleDependency[] getDependencies(); URI[] getLocations(); String getVersion(); String getImportPolicyClassName(); String getLifecyclePolicyClassName(); Manifest getManifest(); ModuleMetadata getMetadata();  }### Answer:
@Test public void testGetLocations() throws Exception { ClassLoader loader = ProxyModuleDefinitionTest.class.getClassLoader(); ProxyModuleDefinition pmd = new ProxyModuleDefinition(loader); assertNotNull(pmd.getLocations()); assertNotSame(pmd.getLocations(), pmd.getLocations()); List<URI> coll = Arrays.asList(pmd.getLocations()); System.out.println(coll); }
