-----------------------------------------
The last commit fixes the cause of the stack trace below (one of the many
problems that sporadically happened with the test code):

position can only be -1 if {{input.read}} returns -1 and was 0 before. Such a
read fail happens at EOF time and shouldn't happen because {{input.isEOF()}}
was checked before. That is just a symptom of the concurrency problems but I'm
fixing it anyway.

> Key: PDFBOX-4559
> URL: https://issues.apache.org/jira/browse/PDFBOX-4559
> Project: PDFBox
> Issue Type: Bug
> Components: Documentation, Rendering
> Affects Versions: 2.0.15
> Environment: Oracle Java 8 update125 on both Mac OS X and centos
> Reporter: Jack
> Priority: Major
> Labels: type1, type1font
> Fix For: 2.0.16, 3.0.0 PDFBox

> I got following error while running a simple parallel rendering code.
> However, the error doesn't happen when I change parallelStream to sequential
> (stream()). Interestingly, both methods will render exact same images. I saw
> a possible related ticket PDFBOX-3654. But seems that issue was fixed. I'd
> like to learn if we have some more bugs related?
> *Sample code*:
> {code:java}
> PDDocument document = PDDocument.load(new File(pdfFilename));
> List<PDDocument> pdfPages = new Splitter().split(document);
> pdfPages.parallelStream().forEach(page -> {
> try {
> PDFRenderer renderer = new PDFRenderer(page);
> renderer.renderImageWithDPI(0, 180, ImageType.RGB); // change dpi to your
> number
> } catch (IOException e) {
> System.out.println(e);
> }
> try {
> pdfPage.close();
> } catch (IOException ignored) {
> }
> });
> try {
> document.close();
> } catch (IOException ignored) {
> }
> {code}

> *Error log*:
> {noformat}
