> While working on TIKA-357 to address a similar problem for charset detection,
> I found an issue with mime identification having to do with the same general
> problem. Tika right now only deals with the first MimeTypes#getMinLength()
> bytes of a magic header to do the sniffing of mime type. With the example
> file attached from Ken Krugler, it's clear that the current min length size
> of 4 * 1024 bytes isn't enough. Extending it to 8K (8 * 1024 bytes) addresses
> this issue and seems to open up more opportunity for mime detection at little
> overhead cost.
