JSON.parseArray(json, 类对象)无限死循环;[BUG]

[liuccc1]

问题描述

简要描述您碰到的问题。
json字符串：[{id:'1',name:'Dean',age:32,entryDate:'2016-06-29 22:23:00'},{id:'2',name:'Yang',age:31}]
java对象：

public class Employee {
    private String id;
    private String name;
    private Integer age;
    private String birthday;
    private Date entryDate;
}

执行List list = JSON.parseArray(json, Employee.class); 陷入无限死循环。应该是以前的fastjson1支持属性无双引号包裹，但是fastjson2里面json字符串的属性名无双引号用这种就会有上述问题。

String str = "[{id:'1',name:'Dean',age:32,entryDate:'2016-06-29 22:23:00'},{id:'2',name:'Yang',age:31}]";
{
    List<Employee> employees = JSON.parseArray(str, Employee.class, JSONReader.Feature.AllowUnQuotedFieldNames);
    assertEquals(2, employees.size());
}

byte[] utf8 = str.getBytes(StandardCharsets.UTF_8);
{
    List<Employee> employees = JSON.parseArray(utf8, Employee.class, JSONReader.Feature.AllowUnQuotedFieldNames);
    assertEquals(2, employees.size());
}
{
    List<Employee> employees = JSON.parseArray(utf8, 0, utf8.length, StandardCharsets.US_ASCII, Employee.class, JSONReader.Feature.AllowUnQuotedFieldNames);
    assertEquals(2, employees.size());
}

assertThrows(JSONException.class, () -> JSON.parseArray(str, Employee.class));
assertThrows(JSONException.class, () -> JSON.parseArray(utf8, Employee.class));
assertThrows(JSONException.class, () -> JSON.parseArray(utf8, 0, utf8.length, StandardCharsets.US_ASCII, Employee.class));
