I see inconsistent ImageNew() failures for CMYK Jpeg Images  (CF10)

Weird problem.


I have a set of test cases that pass just fine loading a known CMYK jpeg via ImageNew().  Later, with no restart of the app server, these same test cases fail.  Again, after a while, the test case passes again.  I've dug into the Java a little bit, and I wonder if the ImageReader implementation being used doesn't switch out once in a while -- like maybe a hashtable of ImageReaders reorders or something.


I know the CMYK is only partially supported, but I could get data with ImageNew and ImageInfo showing it was a CMYK file, then later on, it would throw "Image Not Supported" errors.


Anybody have knowledge of these inner workings to provide some insight?  Smells a bit like a bug to me, but I can't consistently replicate it.
