@ -1026,7 +1026,8 @@ environment, for example.
Environment variables are interpreted as follows:
- present and set to empty string: treated as not present
- env variables set to the empty string are kept as such (set to
empty string, rather than undefined)
- System.getenv throws SecurityException: treated as not present
- encoding is handled by Java (System.getenv already returns
a Unicode string)
