Configure https proxy through http protocol

[jeusdi]

Why this line is hardcoded to use https protocol proxy?

I need to get connectivity to my target through corporate proxy.

I'm used to configure my environment variables like this:

HTTPS_PROXY=http://x.x.x.x:8080
https_proxy=http://x.x.x.x:8080

I'm setting java system properties like:

-Dhttps.proxyHost=x.x.x.x -Dhttps.proxyPort=8080 -DproxySet=true"

Any ideas?
