Hi,
this means that ScratchFileBuffer(s) were created on ScratchFile without
closing them. While a COSDocument will currently automatically close the
ScratchFile, the buffers, using the ScratchFile still exists (there
would be an IOException if a read/write method of the buffer is executed).
There are 2 options coming to my mind for suppressing the debug error
message in case ScratchFile is already closed ( a) check ScratchFile
state before printing message, b) ScratchFileBuffer is listening to
close call of ScratchFile and close itself), but I would rather propose
to fix the source of the problem - the not closed buffer - which I
believe will be an COSStream which is not closed.
In order to do the latter one we would need to have a short code snipped
demonstrating the problem.
Best,
Timo

Subject: 2.0.0-RC2 ScratchFileBuffer not closed!
Hey guys,
Using either 2.0.0-RC1 or 2.0.0-RC2 I am seeing a lot of debug
messages which look like:
"ScratchFileBuffer not closed!"
When I trace this it appears that this is called by `finalize` being
called on the ScratchFileBuffer.
I am opening and closing my PDDocument by using try-with-resources, i.e.
try(final PDDocument doc = PDDocument.load(pdf.asFile)) {
...
}
As far as I can see I am not manually specifying any Scratch files,
are there any known issues with these not being correctly freed in
2.0.0?
Cheers Adam.
