I would update the test to this: | public Map<String, String> compositeSignature; | | public void testMapComposite() throws Exception | { | Field field = getClass().getField("compositeSignature"); | Type mapSignature = field.getGenericType(); | CompositeMetaType result = assertInstanceOf(resolve(mapSignature), CompositeMetaType.class); | MutableCompositeMetaType expected = new MutableCompositeMetaType(HashMap.class.getName(), "HashMap<String,String>"); | expected.addItem("key1", "key1", SimpleMetaType.STRING); | expected.addItem("key2", "key2", SimpleMetaType.STRING); | expected.addItem("key3", "key3", SimpleMetaType.STRING); | expected.freeze(); | | testComposite(expected, result); | | String[] itemNames = {"key1", "key2", "key3"}; | MetaValue[] itemValues = {SimpleValueSupport.wrap("value1"), SimpleValueSupport.wrap("value3"), SimpleValueSupport.wrap("value3")}; | CompositeValueSupport mapValue = new CompositeValueSupport(expected, itemNames, itemValues); | assertEquals("value1", mapValue.get("key1")); | } | Your test will never work, since: | new HashMap<String,String>().getClass() | will just return the erased type, not the generic type.
