Estoy usando AspectJ para interceptar java.net. Socket llamadas.

He creado un aspecto muy simple

after(): call(* java.net.Socket.connect(..)) {
    System.out.println("Connect intercepted!");
}

y aop.xml

<aspectj>

    <aspects>
        <aspect name="com.iggroup.lightstreamer.nwtp.SocketExceptionLoggingAspect"/>
    </aspects>

    <weaver options="-Xlint:ignore -Xset:weaveJavaxPackages=true -Xset:weaveJavaPackages=true">
    </weaver>

</aspectj>

Cuando la pila de llamadas es así, entonces puedo ver la salida de la consola:

java.lang.Exception

Pero nada se desconecta cuando la pila de llamadas es así:

Me pregunto si es porque elsun.net.* los paquetes no se entrelazan debido al tiempo de carga debido a algunas restricciones del administrador de seguridad.

¿Alguien sabe cómo hacer que funcione?sun.net.* paquetes?

Actualización 1

Confirmo que puedo interceptar ells_client.HttpProvider.connectAndGetAnswer llamar, pero no el que está arriba (sun.net.www.protocol.https.HttpsURLConnectionImpl.getInputStream)

Essun.* posible tejer con AspectJ?
