You may need to increase the memory used by the surefire jvm if it is set to
fork.
Here's a config example:
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-surefire-plugin</artifactId>
<version>2.3</version>
<configuration>
<includes>
<include>**/*Test.java</include>
</includes>
<forkMode>once</forkMode>
<!-- need more memory than the default for our unit tests
-->
<argLine>-Xmx1050m -XX:MaxPermSize=128M</argLine>
</configuration>
</plugin>
