This exception also doesn't look directly related to the SM, so we may want to keep it, as you did in `URLImageSource#getDecoder`. 

Removing it changed the behavior, now we can instantiate `ImageConsumerQueue` with a mismatched `ImageRepresentation` image source and `InputStreamImageSource`, but we couldn't before.
