Ouch. Thanks for finding this. Proposed improved code:
```
protected static ImageReader findImageReader(String formatName, String
errorCause) throws MissingImageReaderException
{
Iterator<ImageReader> readers =
ImageIO.getImageReadersByFormatName(formatName);
ImageReader reader;
while (readers.hasNext())
{
reader = readers.next();
if (reader != null && reader.canReadRaster())
{
return reader;
}
}
throw new MissingImageReaderException("Cannot read " + formatName +
" image: " + errorCause);
}
```
