-----------------------------------------------------------------
I added this code just before the place where it happens:
{code}
if (index >= flags.length || index + i >= flags.length)
{ // PDFBOX-2824
for (StackTraceElement[] stea :
Thread.getAllStackTraces().values())
{
for (StackTraceElement ste : stea)
{
System.out.println(ste);
}
System.out.println();
}
}
flags[index + i] = flags[index];
{code}
And then did many builds, until it happened (note that all line numbers in
GlyfSimpleDescript.java are one line higher than in the trunk, because of an
extra import I forgot to delete):

> Key: PDFBOX-2824
> URL: https://issues.apache.org/jira/browse/PDFBOX-2824
> Project: PDFBox
> Issue Type: Bug
> Components: FontBox
> Affects Versions: 2.0.0
> Reporter: Tilman Hausherr
> Priority: Critical
>
> From Kenneth K. in the mailing list:
> I have a client application that convert pdf documents into single page tiff
> images. Since the user export large quantities of documents I use a
> multithreaded approach. Each thread loads it own document and converts the
> pages one by one.
> The pdf file is serialized to the client thread and then each thread executes
> the following code. If I only use 1 thread there is no problem. I checked
> to make sure objects are shared between threads.
> {code}
> docin = PDDocument.load(new
> ByteArrayInputStream(documentResult.getImage().getContent()),true);
> if(null==docin)
> throw new Exception("Invalid PDF document or an occured during
> retrieval");
> int numPages = docin.getNumberOfPages();
> String strPath = getPath(numPages);
> int iPage = 0;
> PDFRenderer renderer = new PDFRenderer(docin);
> for (int i=0;i<numPages;i++)
> {
> PDPage page = docin.getPage(i);
> PDRectangle rect = page.getMediaBox();
> BufferedImage pageImage = null;
> pageImage = renderer.renderImageWithDPI(i, 200f,
> ImageType.BINARY);
> ...
> }
