Exception gets caught somewhere up the call stack, like a webserver returning error 500. It's not the most user-friendly error handling, so you should avoid that whenever you can, but it's not a big problem. In some languages like C++, you'll trigger a crash instead, which can be more of an issue but still isn't nearly as bad as an undetected buffer overflow.
