DicomImageReader for large (>3Gb) US (UltrasoundMultiFrameImageStorage) can not extract all the images (for frames above ~1500 is not working)

Hi,
I have a large (>3Gb) UltrasoundMultiFrameImageStorage dicom file, containing over 2000 image frames.
When i try to retrieve the BufferedImages for the first ~1000 frames it's working fine but for larger frame numbers an exception is thrown:
java.lang.IndexOutOfBoundsException: pos < flushedPos!
at java.desktop/javax.imageio.stream.FileImageInputStream.seek(FileImageInputStream.java:143)
at org.dcm4che3.imageio.plugins.dcm.DicomImageReader.readRaster(DicomImageReader.java:395)
at org.dcm4che3.imageio.plugins.dcm.DicomImageReader.read(DicomImageReader.java:465)

I think the problematic line in this case is in DicomImageReader class the method readRaster:
iis.seek(pixelData.offset() + frameIndex * frameLength);

In my case:
frameIndex = 1492
frameLength = 1440000
The multiply will cause an integer owerflow add the position will be negative.
