Example 1 with HazelcastAPIDelegatingClassloader

use of com.hazelcast.test.starter.HazelcastAPIDelegatingClassloader in project hazelcast by hazelcast.

the class HazelcastProxyFactoryTest method testReturnedProxyImplements_sameInterfaceByNameOnTargetClassLoader.

@Test
public void testReturnedProxyImplements_sameInterfaceByNameOnTargetClassLoader() throws Exception {
    ProxiedInterface delegate = new ProxiedInterface() {

        @Override
        public void get() {
        }
    };
    // HazelcastAPIDelegatingClassloader will reload the bytes of ProxiedInterface as a new class
    // as happens with every com.hazelcast class that contains "test"
    HazelcastAPIDelegatingClassloader targetClassLoader = new HazelcastAPIDelegatingClassloader(new URL[] {}, HazelcastProxyFactoryTest.class.getClassLoader());
    Object proxy = HazelcastProxyFactory.proxyObjectForStarter(targetClassLoader, delegate);
    assertNotNull(proxy);
    Class<?>[] ifaces = proxy.getClass().getInterfaces();
    assertEquals(1, ifaces.length);
    Class<?> proxyInterface = ifaces[0];
    // it is not the same class but has the same name on a different classloader
    assertNotEquals(ProxiedInterface.class, proxyInterface);
    assertEquals(ProxiedInterface.class.getName(), proxyInterface.getName());
    assertEquals(targetClassLoader, proxyInterface.getClassLoader());
}

Example 2 with HazelcastAPIDelegatingClassloader

the class ProcessorClassLoaderTest method createHazelcastMember.

private HazelcastInstance createHazelcastMember() throws MalformedURLException {
    Config config = smallInstanceConfig();
    config.getJetConfig().setResourceUploadEnabled(true);
    // Create a member in a separate classloader without the test classes loaded
    URL classesUrl = new File("target/classes/").toURI().toURL();
    HazelcastAPIDelegatingClassloader classloader = new HazelcastAPIDelegatingClassloader(new URL[] { classesUrl }, // Need to delegate to system classloader, which has maven dependencies like Jackson
    ClassLoader.getSystemClassLoader());
    return HazelcastStarter.newHazelcastInstance(config, classloader);
