Webdev Auto-Reload in 12 Kilobytes, Zero Dependencies

I was served terminal advertisements on a recent Javascript project because its auto-reload dev-dependency pulled in a compromised package. So in retaliation I made my own implementation in Java, with 0 dependencies and low memory usage, using NIO Buffers and FileChannels.

PS: Shameless plug, I'm graduating college late December, and am looking for a job!
