Can't connect to gtalk with jabber notifier via proxy

Hi,

I have sending notifications to GTalk via jabber notifier if I am behind proxy. I've configured notifier as specified in the FAQ:

jabber host: talk.google.com
jabber port: 5222
jabber login: <my login without @gmail.com>
Jabber Domain Name: gmail.com
Is it a SSL Connection? false

I am starting continuum as a service with local account (to be able to read settings.xml where we also have a proxy defined). I have defined proxy in wrapper.conf in the following way:

wrapper.java.additional.9=-Dhttp.proxyHost="<my proxy host name>"
wrapper.java.additional.9.stripquotes=TRUE
wrapper.java.additional.10=-Dhttp.proxyPort="8080"
wrapper.java.additional.10.stripquotes=TRUE
wrapper.java.additional.11=-Dhttp.nonProxyHosts="*.mycompany.com|localhost|127.0.0.1"

I tried host and port with and without quotes, tried to use proxy ip instead of the host name. No result, I get the following exception:

135043 [pool-1-thread-1] ERROR org.apache.maven.continuum.notification.ContinuumNotificationDispatcher:default - Error while trying to use the jabber notifier.
