James Green commented on PDFBOX-2511:
-------------------------------------
This client code driving this is virtually the same that experienced
PDFBOX-1586. I same virtually the same, it's part of a larger application that
does much the same set of operations in various places, in this particular case
it's during our "Print Preview" operation however further tests may break in
other areas I just don't know at this point.
We now have the prospect of needing to revert to our private build that was
mentioned in the above ticket.

> Key: PDFBOX-2511
> URL: https://issues.apache.org/jira/browse/PDFBOX-2511
> Project: PDFBox
> Issue Type: Bug
> Components: Writing
> Affects Versions: 1.8.7
> Reporter: James Green
>
> In our use case we take a large PDF, split into multiple separate document by
> some algorithm, then optionally apply to each document stationary via overlay
> and a varying number of attachments. Each final document is then written to
> an in-memory byte[] for database storage.
> We're seeing an occasional crash when saving this document. It is not
> immediately repeatable so we suspect it's a bad reference after garbage
> collection. Stacktrace to follow.
