javax.net.ssl.SSLPeerUnverifiedException with proxy

Dear all,

I get a SSLPeerUnverifiedException when tyring to login (from one of the samples):

javax.net.ssl.SSLPeerUnverifiedException: peer not authenticated
    at com.sun.net.ssl.internal.ssl.SSLSessionImpl.getPeerCertificates(Unknown Source)

I modified the code to add the proxy:

        VcloudClient.setLogLevel(Level.ALL);
        vcloudClient = new VcloudClient(baseUrl, Version.V1_5);
        vcloudClient.registerScheme("https", 8080, FakeSSLSocketFactory.getInstance());
        vcloudClient.setProxy("lanproxy.t-mobile.at", 8080, "https");
        vcloudClient.login(username, password);

which results in this error; It seems that with the proxy, the FakeSSLSocketFactory is't invoked at all. Furthermore, I have the relevant root certificate in the  fitting keystore.

any Ideas?

regards
