I'm trying to retrieve data from Prometheus with Java and its class for 
creating a URI, which its HttpRequest requires won't accept things like = 
and & so I have to use their URLEncoder, which turns

temperature&step=60s&start=1677302397&end=1677303177

into

temperature%26step%3D60s%26start%3D1677302397%26end%3D1677303177

In my browser if I append the url encoded one to

http://192.168.50.9:9090/api/v1/query_range?query=

I get the error

invalid parameter "start": cannot parse "" to a valid timestamp

If I instead append the original, non-url encoded parameters then it works.
