Mybatis plus returning no rows when IS NULL check included in where clause

Question

No rowing returning while checking reqstatus is null in where clause using mybatis plus

<select id="fetchrow" resultMap="BaseResultMap">
    SELECT * FROM USERS 
    <where>
    reqstatus IS NULL
    AND reqFlag IS NULL
    AND rownum &lt;= 3
    FOR UPDATE SKIP LOCKED
    </where>
<select> 

MyBatis generated query is working in SQL Developer and returning data where as MyBatis Plus returns no rows.

ID  NAME     ReqStatus Reqflag
12  sandhya   (null)    (null)
13  custre    (null)    (null)
14  ewrd      s          t

The above is the table data
