> read operations alter PDLab object
> ----------------------------------
>
> Key: PDFBOX-2047
> URL: https://issues.apache.org/jira/browse/PDFBOX-2047
> Project: PDFBox
> Issue Type: Bug
> Components: PDModel
> Affects Versions: 1.8.4, 1.8.5, 2.0.0
> Reporter: Tilman Hausherr
> Assignee: Tilman Hausherr
> Fix For: 1.8.6, 2.0.0
>
>
> This is a follow-up to PDFBOX-2042 but for PDLab: "A read operation must not
> alter the pdf."
> The problem described PDFBOX-2042 happened because the constructor called
> loadICCProfile(), which called getRangeForComponent(c), which altered its own
> object with (broken) default values. PDLab has no such constructor so Jurajs
> test won't show any problem, but this different test will:
> {code}
> PDLab pdLab = new PDLab();
> COSArray cosArray = (COSArray) pdLab.getCOSObject();
> COSDictionary dict = (COSDictionary)cosArray.getObject(1);
> pdLab.getBlackPoint();
> pdLab.getWhitepoint();
> pdLab.getARange();
> pdLab.getBRange();
> assertEquals("read operations should not change the size of /Lab
> objects", 0, dict.size());
> dict.toString(); // rev 1571125 does stack overflow here in 2.0
> {code}
> removing the assert brings a stack overflow.
