Maruan Sahyoun commented on PDFBOX-1677:
----------------------------------------
Hi
# can you close PDDocument before you close the input stream
# can you do a save copy of the inputPDF byte[] in the method
# can you use a RandomAccessFile in the PDDocument.load call to lower the
memory consumption
When the issue occurs are there multiple threads running? If there are single
threads only is the issue still happening?

> Key: PDFBOX-1677
> URL: https://issues.apache.org/jira/browse/PDFBOX-1677
> Project: PDFBox
> Issue Type: Bug
> Components: PDFReader, PDModel, Utilities
> Affects Versions: 1.8.1, 1.8.2
> Environment: JSF1.1+ PdfBox1.8.2+Tomcat (and Weblogic)
> Reporter: Javier García Sánchez
> Labels: PDPage,, convertToImage(),
> java.lang.IndexOutOfBoundsException
> Original Estimate: 48h
> Remaining Estimate: 48h
>
> Sometimes, a random times, the method PDPage.convertToImage() throw an
> exception like java.lang.IndexOutOfBoundsException.
> I said sometimes, because is a ramdom process which i cannot understand.
> This is my code:
> public byte[] getImageOutputStreamFromPdfFile (byte[] inputPDF) throws
> IOException,Exception{
> logger.info("Utils.getImageOutputStreamFromPdfFile
> (byte[] inputPDF)");
> //resultado
> byte[] result=null;
>
> if (inputPDF!=null && inputPDF.length>0){
> long time = System.currentTimeMillis();
>
> InputStream isPDF = null;
>
>
> //imagen resultado
> ByteArrayOutputStream imageOutputStream = null;
>
> try{
> isPDF = new
> ByteArrayInputStream(inputPDF);
> imageOutputStream = new
> ByteArrayOutputStream();
>
> //pdf
> PDDocument document =
> PDDocument.load(isPDF, true);
> @SuppressWarnings("unchecked")
> List<PDPage> pages =
> document.getDocumentCatalog().getAllPages();
> List<BufferedImage> imagesList = new
> ArrayList<BufferedImage>(
> pages.size());
>
> PDPage pDPage = null;
> BufferedImage auxImage = null;
> // width y height final image
> int maxWidth = 0;
> int totalHeight = 0;
> for (int i = 0; i < pages.size(); i++) {
> pDPage = pages.get(i);
>
> // get Image Page
> auxImage =
> pDPage.convertToImage();
>
> auxImage.flush();
> // maxWidth
> if (auxImage.getWidth() >
> maxWidth) {
> maxWidth =
> auxImage.getWidth();
> }
>
> // totalHeight
> totalHeight +=
> auxImage.getHeight();
>
> // add image to the list
> imagesList.add(i, auxImage);
