Hi David,
thanks for the bug report. You are right and the proposed solution seems
to be a valid fix.
I've created https://issues.apache.org/jira/browse/PDFBOX-5764 to handle
it.

Hello
I think that this is not correct in some cases:
public RandomAccessReadBuffer(ByteBuffer input) {
chunkSize = input.capacity();
IMHO input.limit() shoud be used instead of input.capacity().
When it matters: I have a ByteArrayOutputStream to that is written a PDF
document. Later I want to open the PDF document using PDFBox again. If
I use
part of the internal buffer directly (without copying), eg.
ByteBuffer.wrap(bos.getInternalBuffer(), 0, bos.size()), I get exception
like that:
java.lang.IllegalArgumentException: newPosition > limit: (31556 > 20960)

31556 is the buffer capacity, 20960 is its limit
I think the buffer should not be read beyond its limit.
