I found the problem... One of my co-workers, to read the original TIFF
file, used the same read method you used, but after that here used the
GridCoverageFactory to generate a copy in the first read, im not sure why.
This worked on all TIFF without the Alpha band but with Alpha it generates
the errore above.
Here the code used to read the original TIFF image:
GridCoverageFactory factory = new GridCoverageFactory();
GridCoverage2D gridCopy = factory.create("GridCoverage",
grid.getRenderedImage().copyData(null), grid.getEnvelope());
// Dispose the grid resources to avoid the lock of the tiff file
ImageUtilities.disposeImage(grid.getRenderedImage());
grid.dispose(false);
Thanks a lot for your help!
