pom parent version miss match

i check the svn revision 678620 to do camel loading test, but pom.xml is missmatch with parent's.

the pom.xml in activemq-camel-loadtest

<parent>
<groupId>org.apache.activemq</groupId>
<artifactId>activemq-parent</artifactId>
<version>5.1-SNAPSHOT</version>
</parent>

the pom.xml in activemq

<groupId>org.apache.activemq</groupId>
<artifactId>activemq-parent</artifactId>
<version>5.2-SNAPSHOT</version>
<packaging>pom</packaging>
<name>ActiveMQ</name>

I try to modify the version 5.1 to 5.2 OR 5.2 to 5.1 but all the things cannot run.
