Mybatis : "less than" issue in Select annotations

I am using java7, spring 3 and mybatis

Pom.xml

<org.mybatis-version>3.2.8</org.mybatis-version> <org.mybatis-spring-version>1.2.2</org.mybatis-spring-version> <dependency> <groupId>org.mybatis</groupId> <artifactId>mybatis</artifactId> <version>${org.mybatis-version}</version> </dependency> <dependency> <groupId>org.mybatis</groupId> <artifactId>mybatis-spring</artifactId> <version>${org.mybatis-spring-version}</version> </dependency> 

While using annotation based Select i came across with strange issue where below mentioned code was throwing exception due to use of < (Less then) while > (greater then) works as expected.

<script>
SELECT * FROM STUDENT
WHERE DEPARTMENT_ID = #{depId} <if test='joiningDate != null'> AND STUDENT_ID <= #{joiningDate} </if> </script> 

After googling for a while i find out this issue reported below.

Above issue can be fixed by replacing < (less then) with < as shown below.

<script> SELECT * FROM STUDENT WHERE DEPARTMENT_ID = #{depId} <if test='joiningDate != null'> AND STUDENT_ID &lt;= #{joiningDate} </if> </script> 

I have also came across of suggestion for using using CDATA or ^ in respected scenarios which i haven't given try yet.
