Tilman Hausherr updated PDFBOX-5965:
------------------------------------
Description:
A user (memo for me: on 3.3.2025 16:58) has contacted me with a problem that
involves a token count difference of parsed content stream tokens between
PDFBox 2.0.33 and 3.0.4. It happens when an inline image is close to the end of
the file, and is followed by two "Q" operators. The two "Q" operators are
ignored despite the rewind() in PDFStreamParser. The problem goes away by
replacing {{new NonSeekableRandomAccessReadInputStream(decoderStream)}} with
{{new RandomAccessReadBuffer(decoderStream)}} in {{PDPage}}. It does not happen
in PDFBox 3.0.2.
I have a file that reproduces the problem but I doubt I can share it, I will
try to find or create something.
