When a server responds with Content-Length: 0 during the server resource pack download, the download fails with a division-by-zero error.

The steps to reproduce are to write a web server that returns a Content-Length: 0 header and point the server resource pack URL to it. The exact resource pack used doesn't matter since the issue is in the headers, not arbitrary data that may or may not be exist or associated with any file.
Can you provide steps to reproduce? What was the resource pack?
