I have a system on which both NO_PROXY and no_proxy are defined already.

I have a program I am trying to execute in my pipeline that reads only NO_PROXY.

I tried to override NO_PROXY like:

withEnv(["NO_PROXY=$NO_PROXY,otherthingy"])

but it mistakenly edits the 'no_proxy' version instead, not touching the NO_PROXY one.
