I do not have time to quickly investigate the issue,
but a quick hack si drawn by the following snippet.
....
//create your coverage
...
//snippet
final PlanarImage image=(PlanarImage) coverage.getRenderedImage();
final Object
r=image.getProperty(ImageReadDescriptor.PROPERTY_NAME_IMAGE_READER);
if(r instanceof ImageReader)
try{
((ImageInputStream)((ImageReader)r).getInput()).close();
}catch (Exception e) {
}
coverage.dispose(true);
reader.dispose();
try{
in.close();
assertTrue(((File)o).delete());
assertFalse(((File)o).exists());
//end of snippet
Note that you would probably add more checks when you try to get the
reader out of your original coverage. The code I put there is a bit
convolute and may easily fail if no reader property is attached to the
image.
