Unable to start embedded Google App Engine Server for Integration Tests

I am trying to start an embedded Google App Engine Development Server (sdk 1.7.3) inside a @BeforeClass of a test suite run by the maven failsafe plugin. The code that should start it looks like this:

private static final String HOST = "0.0.0.0";
private static final int PORT = 8887;
private static DevAppServer devAppServer;


@BeforeClass
public static void setup() throws Exception {
    log.debug("Starting development server");
    File appRootDir = new File("target/visualize-1.0.war");
    DevAppServerFactory devAppServerFactory = new DevAppServerFactory();
    devAppServer = devAppServerFactory.createDevAppServer(appRootDir, HOST, PORT); 
    devAppServer.start();
}

However during the call to createDevAppServer, I get a security exception:

java.security.AccessControlException: access denied (java.lang.RuntimePermission setContextClassLoader)
at java.security.AccessControlContext.checkPermission(AccessControlContext.java:374)
at java.security.AccessController.checkPermission(AccessController.java:546)

debugging the security exception with -Djava.security.debug=access,failure I see:

  access: access allowed (java.io.FilePermission    /home/me/.m2/repository/com/google/appengine/appengine-tools-sdk/1.7.3/appengine-tools-sdk-1.7.3.jar read)

What am I doing wrong?

Actually, you're not supposed to call GAE the way you've done (hint: GAE has so many patches for dealing with security its simply not worth it)

However, the maven-gae-plugin does have gae:start and gae:stop specially for IT.

This is how I use it for IT:

<plugin>
    <groupId>net.kindleit</groupId>
    <artifactId>maven-gae-plugin</artifactId>
    <version>0.9.4</version>
    <dependencies>
        <dependency>
            <groupId>net.kindleit</groupId>
            <artifactId>gae-runtime</artifactId>
            <version>1.6.6</version>
            <type>pom</type>
        </dependency>
    </dependencies>
    <executions>
        <execution>
            <id>start-integration-test</id>
            <phase>pre-integration-test</phase>
            <goals>
                <goal>start</goal>
            </goals>
        </execution>
        <execution>
            <id>stop-integration-test</id>
            <phase>post-integration-test</phase>
            <goals>
                <goal>stop</goal>
            </goals>
        </execution>
    </executions>
</plugin>
<plugin>
    <groupId>org.apache.maven.plugins</groupId>
    <artifactId>maven-failsafe-plugin</artifactId>
    <version>2.12</version>
    <executions>
        <execution>
            <id>it</id>
            <phase>integration-test</phase>
            <goals>
                <goal>integration-test</goal>
            </goals>
        </execution>
    </executions>
</plugin>
