mybatis 使用<include ><property/></include>组合向<sql>标签动态传递值程序出错？

例子：
<sql id="userColumns"> ${alias}.id,${alias}.username,${alias}.password </sql>
<select id="selectUsers" resultType="map">
select
<include refid="userColumns"><property name="alias" value="t1"/></include>,
<include refid="userColumns"><property name="alias" value="t2"/></include>
from some_table t1
cross join some_table t2
</select>

我代码中一使用<property>这个就一直循环报 Logging initialized using 'class org.apache.ibatis.logging.stdout.StdOutImpl' adapter.去除<property >，把<sql>里内容写死，就不会，这是什么原因？版本 mybatis-3.2.8;
