I recently downloaded neo-sdk-javawed-1.4.17.5.
While trying to resolve a problem, I looked inside neo.bat, and I think there's an error.
In my copy of neo.bat, line 41 reads:
if defined HTTPS_PROXY_PORT (
I think this should be
if defined HTTP_PROXY_PORT (
It's not a serious issue, but it will affect the detection and error reporting of a bad environment variable.
Normally, I presume if HTTPS_PROXY_PORT is defined, HTTP_PROXY_PORT is as well, and vice versa, so there's no issue.
