Arquillian managed container : Server not detected - jboss7.x

Question

So I "installed" Arquillian in my jboss project. I used managed container. The server is starting up when I launch my test class. I increased the timeout to 120s instead of 60s to be sure. The problem is that once the server is launched (an i can navigate in the web application), the test is never launched...
On the JUnit tab nothing is happening until the 120s are over and then I get a timeout as if the server that was started is not detected.
Once this error occured, the server is shutdown, so there is has to be a link right ?
Did anyone had the same error ?
Thanks
CODE:
this is the container in arquilian.xml
<container qualifier="jbossas-managed" default="true">
<configuration>
<property name="jbossHome">C:\Developpement\jboss-as-7.1.3.Final</property>
<property name="startupTimeoutInSeconds">120</property>
<property name="javaVmArguments">-server -Xms64m -Xmx6g -XX:MaxPermSize=1024m -Dorg.jboss.as.logging.per-deployment=false -Djava.util.Arrays.useLegacyMergeSort=true -Xrunjdwp:transport=dt_socket,address=8180,server=y,suspend=y</property>
<property name="managementPort">8180</property>
<property name="allowConnectingToRunningServer">true</property>
</configuration>
I use this in my pom file:
<dependency>
<groupId>org.jboss.as</groupId>
<artifactId>jboss-as-arquillian-container-managed</artifactId>
<version>7.1.3.Final</version>
<exclusions>
<exclusion>
<groupId>google-collections</groupId>
<artifactId>google-collections</artifactId>
</exclusion>
</exclusions>
</dependency>
<dependency>
<groupId>org.jboss.logmanager</groupId>
<artifactId>jboss-logmanager</artifactId>
<version>1.2.1.GA</version>
</dependency>
<dependency>
<groupId>org.jboss.arquillian.junit</groupId>
<artifactId>arquillian-junit-container</artifactId>
<version>1.0.4.Final</version>
</dependency>
This is my test file:
#RunWith(Arquillian.class)
public class BasculeTest {
private static final int COMPLETE = 0;
private static final int MONTH_INCREMENTATION = 1;
private static final int BASCULE = 2;
private static final int YEAR_INCREMENTATION = 3;
// #Inject CompteursCongesUpdate compteursCongesUpdate;
#Deployment
public static Archive<?> createTestArchive() {
WebArchive war = ShrinkWrap.create(WebArchive.class, "test.war").addClass(CompteursCongesUpdate.class)
.addAsWebInfResource("test-persistence.xml", "classes/META-INF/persistence.xml")
.addAsWebInfResource(EmptyAsset.INSTANCE, "beans.xml");
return war;
}
#Test
public void testBascule() {
System.out.println("------------------------------- Début TEST -------------------------------");
try {
// compteursCongesUpdate.updateCompteursConges(new Date(), MONTH_INCREMENTATION);
// System.out.println("test +" +compteursCongesUpdate);
System.out.println("--------");
} catch (Exception e) {
e.printStackTrace();
Assert.fail("Une exception a ete levee");
}
Assert.fail("Not yet implemented");
}
}
What I can do now is start the server normally (without executing the test class with junit) and afterwards execute the test class, once the server is runnng. Then I get a new error from log4j: nosuchfielderror: NO_FORMAT
java.lang.NoSuchFieldError: NO_FORMAT
