1.2.71版本,在JDK1.7下运行JSON.parseObject时，报错java.lang.ClassNotFoundException: java.time.LocalDateTime

你好：
在1.2.71版本下，使用如下方法测试可以复现。JDK版本1.7.
public class DbInfoTest {
public static void main(String[] args) throws Exception {
String json = "{"test":"test"}";
Test t = JSON.parseObject(json,Test.class);
System.out.println(t.test);
}
}
public class Test {
public String test;
}
报错信息：

如果注释掉JavaBeanDeserializer的1460行value = TypeUtils.castToLocalDateTime(value, format);则可以正常运行。
else if (format != null && (paramType instanceof Class) && (((Class) paramType).getName().equals("java.time.LocalDateTime"))) {
value = TypeUtils.castToLocalDateTime(value, format);
}

确实有这个bug存在，还是回退到1.2.70
