'jms-destinations' section disappears from config file

Steps to reproduce:
1. Unpack fresh jboss 7.1.0CR1b from here: http://download.jboss.org/jbossas/7.1/jboss-as-7.1.0.CR1b/jboss-as-7.1.0.CR1b.tar.gz
2. Open standalone-full.xml config file and remove this:

<jms-topic name="testTopic">
<entry name="topic/test"/>
</jms-topic>

So, jms-destinations section should look like this:
<jms-destinations>
<jms-queue name="testQueue">
<entry name="queue/test"/>
</jms-queue>
</jms-destinations>

3. Start the server: bin/standalone.sh --server-config=standalone-full.xml
4. Deploy 'helloworld' quickstart: mvn clean package jboss-as:deploy

Results:
jms-destinations section (with 'testQueue') completely disappears from the config file.

I did it on JBoss AS 7.0.2 (with standalone-preview.xml, since there is no standalone-full.xml there), and everything works fine, i.e. jms-destinations section is not removed.
