So far I did not find anything comparable to replace Java for website server language. Go is a terrible extremely verbose language without vital features. JavaScript on Node is limited by single-thread and JavaScript itself is a terrible language (along with other dynamic languages like PHP, Python, Perl, Ruby). Rust is awesome, but I don't think that it'll be ever usable for mediocre developers, therefore it can't be a safe choice for ordinary project.
The only reasonable alternative is C#. But it has to go a long way to reach Java's level of stability and trust on non-Windows servers.
