Maven Surefire runs out of memory

I’m running a complicated integration test, and needed to allocate memory appropriately – MAVEN_OPTS was used to increase memory, and I still ran into an issue with MAVEN out-of-memory.  To fix the issue, I had to use the Surefire argsline:  <plugins>   <plugin>      <groupId>org.apache.maven.plugins</groupId>      <artifactId>maven-surefire-plugin</artifactId>      <configuration>         <argLine>-Xms2G -Xmx2G</argLine>      </configuration>   </plugin></plugins>
