Description of problem:
Running simple attached reproducer in maven, NPE is raised.


Version-Release number of selected component (if applicable):
0.18-2


How reproducible:
100%


Steps to Reproduce:
1. Install junit, spring-framework and maven
2. unzip attachment, optionally modify brokerlist in MrgmNpeTest-context.xml to whatever else than default "localhost"
3. mvn test
4. If repeating the test, ensure that maven repository contains proper jar files!!! It automatically tries to _download_ files from qpid.apache.org, ignoring whatever is installed. To replace maven repository, do:
cp -f /usr/share/java/qpid-common-0.18.jar /root/.m2/repository/org/apache/qpid/qpid-common/0.18/qpid-common-0.18.jar 
cp -f /usr/share/java/qpid-client-0.18.jar /root/.m2/repository/org/apache/qpid/qpid-client/0.18/qpid-client-0.18.jar
(and re-run the test with -o option to make maven offline)
