How to setting proxy for osmosis?

I'm trying to use osmosis to update my data ( http://wiki.openstreetmap.org/wiki/Minutely_Mapnik ) but I'm facing the follow error:

org.openstreetmap.osmosis.core.OsmosisRuntimeException: Unable to read the state from the server.

I'm already done export JAVACMD_OPTIONS="-Dhttp.proxyHost=MY_PROXY -Dhttp.proxyPort=6060 -Dhttp.proxyUser=MY_USER-Dhttp.proxyPassword=MY_PASSWORD" but with no success. I'm able to access this URL using the browser.

I know... 407 is for Authentication. The setting I'm using is correct for sure or my browser will give same error.

One more information: as seen in (How to configure Geoserver to use a proxy when accessing external services?) I'm facing same problem in Geoserver. SOME external WMS services gives me same 407 error, others don't.

I think this is because of proxy auth implementation inside the code (osmosis and geoserver may be using same method): https://stackoverflow.com/questions/17183277/http-error-407-proxy-authentication-required
