[alibaba/fastjson]缺少默认构造函数导致无法反序列化

Info类只有构造函数Info(String address)，则无法反序列化admin字段，如果加上默认构造函数 public Info() { } 则可以反序列化admin字段

public class Issuexxxx extends TestCase {
    public void test_for_issue() throws Exception {
        String json = "{\"address\":\"1\",\"admin\":true}";
        Info info = JSON.parseObject(json, Info.class);
        assertTrue(info.isAdmin());
    }

    public class Info {
        private String address;
        private boolean admin;

        public Info(String address) {
            this.address = address;
        }

        public String getAddress() {
            return address;
        }

        public void setAddress(String address) {
            this.address = address;
        }

        public boolean isAdmin() {
            return admin;
        }

        public void setAdmin(boolean admin) {
            this.admin = admin;
        }
    }
}
