With reasonable compile options (e.g. -wall), it is issuing a warning. Every compiler config I used out-of-the-box via some IDE will show that warning. It's bad defaults of the compiler maybe, but hardly the fault of the language itself. Any beginners tutorial has to contain the compile and/or run command, no matter which language. At least C++ has unsigned types. Java doesn't even warn about `new int[-30]` and similar fun stuff (at least not generally).
