---------------------------------------
Summary: ArrayIndexOutOfBoundsException in
GlyfSimpleDescript.readFlags() when multithreading
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
>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);
...
}
{code}
{code}
