Open Tiff image failed with imageio package

Question

I'm trying to open tiff files with javax.imageio.ImageReader. When openning the image file, "bad.TIF" with the following codes, I got an error. However, I can open the image with "Windows Picture and Fax Viewer" (WPFV). After I opened/saved as File "good.TIF" with WPFX, I can open the image with the progarm. Would someone please help? Thanks.
Error position is 2
java.lang.ArrayIndexOutOfBoundsException: 2012

Can you upload the bad tiff to an [image hosting site|http://www.imagehosting.com/]?
In general, when you set the input stream on a reader for a second time, it's a good idea to call reset.
errorPos = 2;
file = new File(testFile2);
tiffStream = ImageIO.createImageInputStream(file);
reader.reset();  <----- this line
reader.setInput(tiffStream);
tiffImage = reader.readAll(0, reader.getDefaultReadParam());I don't think that's the source of your problems though. You can add an IIOReadUpdateListener and a IIOReadWarningListener to the reader to see just how far it gets just before the exception is thrown. It may very well just be a badly saved tiff, or it could be a tiff image reader bug.

BTW, which version of JAI-ImageIO are you using?
