mybatis jdk11遇到问题,jdk7没有问题：Mybatis报错invalid comparison: java.lang.StringBuffer and java.lang.String

jdk7 无问题

​​​​​​​<select id="find" resultMap="result" parameterType="map">
       select * from user where 1=1 
       <if test="_CONDITION != null and _CONDITION != ''">
            ${_CONDITION}
        </if>
</select>

jdk 11 报错invalid comparison: java.lang.StringBuffer and java.lang.String

​​​​​​​<select id="find" resultMap="result" parameterType="map">
       select * from user where 1=1 
       <if test="_CONDITION != null and _CONDITION != ''">
            ${_CONDITION}
        </if>
</select>

正确写法：

​​​​​​​<select id="find" resultMap="result" parameterType="map">
       select * from user where 1=1 
       <if test="_CONDITION != null">
            ${_CONDITION}
        </if>
</select>
