List<String>反序列化时会生成双倍数据

[monkey1993]

版本：2.0.40 例如：[{"array":["test1", "test2", "test3"]}]序列化为Java对象，再反序列化为Json，就变成了[{"array":["test1","test2","test3","test1","test2","test3"]}]。元素数量变成双倍。代码如下：

public class JsonTest {

	static class ListTest {
		public final List<String> array;

		public ListTest(List<String> array) {
			this.array = array;
		}
	}

	@Test
	public void test() {
		String json = "[{\"array\":[\"test1\", \"test2\", \"test3\"]}]";
		List<ListTest> values = JSONObject.parseObject(json, TypeReference.collectionType(List.class, ListTest.class));
		System.out.println(JSONObject.toJSONString(values)); // [{"array":["test1","test2","test3","test1","test2","test3"]}]
	}
}
