### Question:
BoonJsonMapper implements JsonMapper { @Override public String toJson(Object object) { return serializer.get().serialize(object).toString(); }  @Override Object fromJson(String json); @Override T fromJson(String json, Class<T> cls); @Override List<T> fromJsonArray(String json, Class<T> componentClass); @Override String toJson(Object object); @Override Map<K, V> fromJsonMap(String json, Class<K> componentClassKey, Class<V> componentClassValue);  }### Answer:
@Test public void badSerializer() throws Exception { String json = QBit.factory().createJsonMapper().toJson(Lists.list(1, 2, null, 3)); puts(json); assertNotNull(json); assertEquals("[1,2,null,3]", json); json = JsonFactory.toJson(Lists.list(1, 2, null, 3)); puts(json); assertNotNull(json); assertEquals("[1,2,null,3]", json); }
