> The current implementation of {{EnvironmentUtil.toStrings()}} will turn an empty map
into a null array. The {{CommandLauncher}} implementations will then pass this array to {{Runtime.exec()}}.
However, passing in {{null}} for the env argument means to inherit the enviroment, this is
not the same as using an empty environment as specified by the caller. In other words, the
semantics of a null map and an empty map clash which I believe shouldn't.
> I suggest to have {{EnviromentUtils.toStrings()}}
> - output an emtpy array upon input of an empty map
> - output {{null}} upon input of {{null}} (primarily to ease usage, e.g. in the {{CommandLauncher}}'s)
