This test case is serializing GridCoverage2D, not RenderedImage. Like mentioned
in my previous email, GridCoverage2D is already made serializable using the
technic mentioned by Christian.

If you have a GridCoverage2D instance, you can do:
// Writting
ByteArrayOutputStream buffer = new ByteArrayOutputStream();
ObjectOutputStream out = new ObjectOutputStream(buffer);
out.writeObject(theCoverage);
out.close();
byte[] asArray = buffer.getArray();
// Reading
ObjectInputStream in = new ObjectInputStream(new ByteArrayInputStream(asArray));
GridCoverage2D theCoverage = (GridCoverage2D) in.readObject();
in.close();
