I call nsIURIChecker asyncCheck() from javascript to check the URI does not yet
exists

when the URI is http:// URI or an existing file:// URI it calls onStartRequest
but if URI is an unexisting file:// URI it never calls onStartRequest and never
returns

Reproducible: Always

Steps to Reproduce:
1. call asyncCheck with an unexisting file:// URI
2. see if onStartRequest is called
3.

Actual Results:  
onStartRequest does not get called

Expected Results:  
call onStartRequest

Hrm... when I tested this just now, I find that AsyncCheck throws an exception.
 I agree that it should call the API instead to report the non-existant file in
a consistent manner.  You should be able to hack around this problem until that
is fixed.

This is not a critical bug.

I agree. It does throw an exception and I can use that now that I finally
understand what it is doing.

And yes I would still vote to change it to use the normal API. I was promised in
some documentation to be able to treat file:// http:// etc. URIs with the same
routines and let mozilla take care of the underlying protocol handling and I'm
trying to utilize it as much as I can :-).
