public void createDynamicClass_Twice() throws Exception {
    DynamicClassLoader dcl = new DynamicClassLoader(DynamicClassLoaderTestSuite.class.getClassLoader());
    assertNull(dcl.getClassWriter(MY_CLASSNAME));
    Class<?> dynamicClass = dcl.createDynamicClass(MY_CLASSNAME);
    assertNotNull(dynamicClass);
    assertEquals(MY_CLASSNAME, dynamicClass.getName());
    EclipseLinkClassWriter writer = dcl.getClassWriter(MY_CLASSNAME);
    assertNotNull(writer);
    Class<?> dynamicClass2 = dcl.createDynamicClass(MY_CLASSNAME);
    assertSame(dynamicClass, dynamicClass2);

    DefaultConstructor entity = (DefaultConstructor) dynamicClass.getConstructor().newInstance();
    assertNotNull(entity);
    assertNotNull("DCL does not contain expected writer", dcl.getClassWriter(MY_CLASSNAME));
    dcl.addClass(MY_CLASSNAME, DefaultConstructor.class);
    EclipseLinkClassWriter secondWriter = dcl.getClassWriter(MY_CLASSNAME);
    assertSame(firstWriter, secondWriter);
