Description

I am getting an exception when I try to call SqlSessionFactoryBuilder.build. The exception is:
Exception in thread "main" org.apache.ibatis.exceptions.IbatisException:

1. 1. 1. Error building SqlSession.
      2. The error may exist in my/test/DbMapper.xml
      3. The error occurred while processing mapper_resultMap[TestResult]
      4. Cause: org.apache.ibatis.builder.BuilderException: Error parsing SQL Mapper Configuration. Cause: java.lang.RuntimeException: Error parsing Mapper XML. Cause: java.lang.IllegalArgumentException: Result Maps collection already contains value for my.test.DbMapper.TestResult

The configuration files I have are:
config2.xml
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE configuration
PUBLIC "-//ibatis.apache.orgg//DTD Config 3.0//EN"
"http://ibatis.apache.org/dtd/ibatis-3-config.dtd">

<configuration>
<typeAliases>
<typeAlias alias="Label" type="java.awt.Label" />
</typeAliases>

<environments default="development">
<environment id="development">
<transactionManager type="JDBC"/>
<dataSource type="POOLED">
<property name="driver" value="oracle.jdbc.OracleDriver"/>
<property name="url" value="jdbc:oracle:thin:@${server}:${port}:${instance}"/>
<property name="username" value="${username}"/>
<property name="password" value="${password}"/>
</dataSource>
</environment>
</environments>

<mappers>
<mapper resource="my/test/DBMapper.xml"/>
</mappers>
</configuration>

DBMapper.xml
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE mapper
PUBLIC "-//ibatis.apache.org//DTD Mapper 3.0//EN"
"http://ibatis.apache.org/dtd/ibatis-3-mapper.dtd">
<mapper namespace="my.test.DbMapper">
<resultMap id="TestResult" type="Label">
<result property="text" column="test"/>
</resultMap>

<select id="selectTest" resultMap="TestResult">
select * from test
</select>
</mapper>

I found out that the problem reproduces only when I have the following interface defined:
package my.test;

public interface DbMapper {
public java.awt.Label selectTest();
}

Somehow, it parses the xml again and it gives the exception.
