Hello Andreas,
Thanks, yes the first test was a mistake.
To alleviate the concern I have ensured the code verifies the document being
read is there and exactly as expected.
Acrobat 8 says there was an error opening this document, however PDF
Debugger does not complain.
I try it two ways,
Using an input stream:
PDDocument document = Loader.loadPDF(fis);
corruptPDFDocument("inputStreamSave", document);
Using a File
PDDocument document = Loader.loadPDF(file);
corruptPDFDocument("classLoaderSave", document);
And all I do is
document.save(tempFile);
document.close();
Any thoughts very much appreciated, I am stuck.
Alex

Works fine for me using the current trunk and my own code
Your test cases are probleatic.
The first one doesn't make that much sense, there isn't any PDDcoument.save
involved.
The second and the third one are using the very same file name. The only
difference is the current timestamp. But there is/was an issue on windows
systems where those timestamps aren't accurate so that those are maybe the
same if they are close enough. Saying, maybe oen tests overwrites the output
of the other one
Maybe you should follow Tilmans comment and double check if the ressources
are copied without filtering
