Calls to ObjectMapper.addMixInAnnotations on an instance returned by ObjectMapper.copy() are ignored #245
Description
Below is a chunk of unit test that demonstrates this problem. It should be easy to reproduce with any POJO. I'm using version 2.2.2
@JsonFilter(PortletRenderExecutionEventFilterMixIn.FILTER_NAME)
private interface PortletRenderExecutionEventFilterMixIn {
static final String FILTER_NAME = "PortletRenderExecutionEventFilter";
}
private PortalEvent createEvent() {
final String sessionId = "1234567890123_system_AAAAAAAAAAA";
final PortalEvent.PortalEventBuilder eventBuilder = new PortalEvent.PortalEventBuilder(this, "example.com", sessionId, SystemPerson.INSTANCE, null);
return new PortletRenderExecutionEvent(eventBuilder, new MockPortletWindowId("pw1"), "fname1", 123450000, Collections.<String, List<String>>emptyMap(), false, false);
}
@Test
public void testMixinNoCopy() throws Exception {
ObjectMapper mapper = new ObjectMapper();
mapper.findAndRegisterModules();
mapper.addMixInAnnotations(Object.class, PortletRenderExecutionEventFilterMixIn.class);
final FilterProvider filterProvider = new SimpleFilterProvider().addFilter(PortletRenderExecutionEventFilterMixIn.FILTER_NAME, SimpleBeanPropertyFilter.filterOutAllExcept("fname", "executionTimeNano", "parameters"));
final ObjectWriter portletEventWriter = mapper.writer(filterProvider);
final String result = portletEventWriter.writeValueAsString(createEvent());
assertEquals("{\"@c\":\".PortletRenderExecutionEvent\",\"fname\":\"fname1\",\"executionTimeNano\":123450000,\"parameters\":{}}", result);
}
/**
