Array out of bounds exception while parsing

I get this error when I try to parse the file `src/main/java/org/owasp/webgoat/webwolf/FileServer.java` from Webgoat (https://github.com/WebGoat/WebGoat/releases/tag/v2023.8). The parser throws an array out of bounds exception.

Stack trace:

```

Is there some workaround on this?
