I am experiencing an exception in reading gridcoverages as parts of an imagemosaic.
Not sure what the reason is, but here is what I came up with up to now.
The error is:
Error: One factory fails for the operation "Scale"
Occurs in: javax.media.jai.ThreadSafeOperationRegistry
Full trace is:

Loading the jai-core source, I noticed that the NPE is due to the fact that in GeometricOpImage the call on
int numBands = getSampleModel().getNumBands();
fails because the SampleModel is missing.
Have not been able to understand why.
