Tim Allison commented on TIKA-3429:
-----------------------------------
That sounds frustrating. It feels to me like detection and loading that 7k xml
file of mimes is at the heart of what Tika does. Which components of Tika are
you using that don't require it?
If the problem is that Tika should error out earlier or if there's a common use
case for not needing detection, we should fix that. What's your sense of what
a fix would look like?

> Here's the text of that issue
> I'm not sure the problem is spring boot, but I'm having problems finding it.
> The Jar is currently taking 3 seconds (9 if I live out tiered) to run on my
> system. Just to error out due to missing options and do nothing.
