Tilman Hausherr updated PDFBOX-2685:
------------------------------------
Description:
>From [~torakiki]:
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.
