The ImageReader.readAll method takes an Iterator containing ImageReadParam objects, which may be interspersed with null values indicating a default value. The code to retrieve these ImageReadParam objects incorrectly calls Iterator.next() twice per iteration, resulting in a NoSuchElementException. The second call to next() should reuse the object retrieved from the first call.
