Use Kale behind a proxy

Is it possible to use Kale behind a proxy?
After some googling I've found that the parameters could be used
java -Dhttp.proxyHost=xx.xx.xx.xx -Dhttp.proxyPort=xxxx -jar kale-1.8.1-standalone.jar login

But I'm still having a
A GET to: https://api.ng.bluemix.net/v2/info triggered an unexpected exception: java.net.ConnectException: Connection timed out: no further information

Let me know if you have some information. TY

I'm not in a good position to try access through a proxy. Oracle's documentation is https://docs.oracle.com/javase/7/docs/api/java/net/doc-files/net-properties.html

If you are lucky, the easy setting is probably java.net.useSystemProxies. If that does not work for you, I'm fairly sure you'll need to use the https variants: https.proxyHost and https.proxyPort.
