java.Sicherheit.AccessControlException bei der Verwendung von Ant, aber läuft ok, beim Aufruf von java aus Konsole

Habe ich Folgendes Ant < java - > Aufgabe:

<property name="classpath-run.msg" refid="run.classpath"/>
<echo message="running the app with classpath = ${classpath-run.msg}"/>
<echo message="Java version used (ant.java.version): ${ant.java.version}"/>
<echo message="Java version used (    java.version): ${java.version}"/>
<java classname ="${project.MainClass.name}">
    <permissions>
        <grant class="java.security.AllPermission"/>
        <grant class="javax.management.MBeanTrustPermission" action="register"/>  
    </permissions>
    <classpath refid="run.classpath"/>
</java>

Wenn ich Ant die Ausführung der Aufgabe versagt (siehe trace unten). Wenn ich copy-paste die echo classpath und mein code von der Befehlszeile aus mit java -classpath .. die Ausführung erfolgreich!

In beiden Fällen die gleiche version von java verwendet wird.

Wie ist es möglich, dass ich beobachte das unterschiedliche Verhalten ? Ein java.Sicherheit.AccessControlException sitzt an der Wurzel der stacktrace, aber ich habe bereits zugegeben mein Ant java Aufgabe aller Sicherheit, Berechtigungen, einschließlich, explizit die MBeanTrustPermission für die Aktion registrieren der auch erscheint in der Stapel-Ablaufverfolgung.

Trace (bei der Ausführung unter Ant) finden sich unter:
