             Summary: COSInteger is mutable
                 Key: PDFBOX-2685
                 URL: https://issues.apache.org/jira/browse/PDFBOX-2685
             Project: PDFBox
          Issue Type: Bug
    Affects Versions: 1.8.8, 1.8.9, 2.0.0
            Reporter: Tilman Hausherr
             Fix For: 2.0.0


>From [~avacondio]:
They are cached and they are mutable so this:
{code}
        COSInteger cosint = COSInteger.get(10);
        cosint.setValue(50);
        //lets move to a totally unrelated part of my software
        System.out.println(COSInteger.get(10));
{code}
prints COSInteger(50) so basically I ask for a 10 and get a 50, isn't it weird
(and error prone)? ... or the way around, I call cosint.setValue(50) at
some point in the software and that makes it a 50 everywhere I used
COSInteger.get(10).

That's of course also true for the other mutable attributes setDirect and
setNeedToBeUpdate.
