Examples with Module java.lang.Module used on opensource projects

Example 1 with Module

use of java.lang.Module in project openj9 by eclipse.

the class Test_Class method test_forName.

/**
 * @tests java.lang.Class#forName(java.lang.String)
 * @tests java.lang.Class#forName(java.lang.Module, java.lang.String)
 */
@Test
public void test_forName() {
    try {
        // package java.rmi exported by module java.rmi
        Class<?> jrAccessExceptionClz = Class.forName("java.rmi.AccessException");
        AssertJUnit.assertNotNull(jrAccessExceptionClz);
        if (!jrAccessExceptionClz.getProtectionDomain().implies(ALL_PERMISSION)) {
            AssertJUnit.fail("java.rmi.AccessException should have all permission!");
        }
        Module jrModule = jrAccessExceptionClz.getModule();
        Class<?> jrAlreadyBoundExceptionClz = Class.forName(jrModule, "java.rmi.AlreadyBoundException");
        if ((jrAlreadyBoundExceptionClz == null) || !jrAlreadyBoundExceptionClz.getProtectionDomain().implies(ALL_PERMISSION)) {
            AssertJUnit.fail("java.rmi.AlreadyBoundException should have all permission as well!");
        }
    } catch (ClassNotFoundException e) {
        AssertJUnit.fail("Unexpected ClassNotFoundException: " + e.getMessage());
    }
}

    return builder.create();
}

Example 3 with Module

use of java.lang.Module in project openj9 by eclipse.

the class MyLoader method dumpModules.

private void dumpModules() {
    HashSet<Option> opts = new HashSet<>(Arrays.asList(new Option[] { Option.RETAIN_CLASS_REFERENCE, Option.SHOW_HIDDEN_FRAMES, Option.SHOW_REFLECT_FRAMES }));
    List<StackFrame> frameList = (StackWalker.getInstance(opts)).walk(s -> s.collect(Collectors.toList()));
    for (StackFrame f : frameList) {
        Module frameModule = f.getDeclaringClass().getModule();
        if ((null != frameModule)) {
            ModuleDescriptor d = frameModule.getDescriptor();
            if (null != d) {
                StackTraceElement e = f.toStackTraceElement();

                if (null != modName) {
                    assertEquals(modName, e.getModuleName(), "Wrong module name");
