------------------------------
Summary: Statically cached COS objects are mutable
Key: PDFBOX-3320
URL: https://issues.apache.org/jira/browse/PDFBOX-3320
Project: PDFBox
Issue Type: Bug
Components: Parsing
Affects Versions: 1.8.11
Reporter: Petras
The range of {{COSInteger}} (from -100 to 256) instances, {{COSBoolean}}, many
{{COSName}} instances and {{COSNull}} objects are statically cached in
corresponding classes. Though such such kind of cached objects are supposed to
be immutable, they are not: they inherit and do not block from modification
parent {{COSBase}} class properties {{direct}} and {{needToBeUpdate}}. As these
are properties are set during parsing and modification, and considered during
writing the document, their mutability affects both the objects within the same
document (when ex. the same COSNumber value from the cached range is used in
different contexts both direct and indirect), as well as other documents, which
might parsed and saved using the same classloader.
