Timo Boehme commented on PDFBOX-4601:
-------------------------------------
For me this is a quite strange behavior (e.g. fileLen after: 131072, raf
length: 65536): after setting the RAF size and checking it does not report the
new size. Somehow it seems the file system does not report the correct new size
(while testing on my end the set length is immediately also reported on
raf.length()). Is this a special behavior on the AWS filesystem or JDK? It
seems there is some caching or lazy propagation of IO operations ...

> {{Error in pdf consolidation: Expected scratch file size of 196608 but found
> 192512.}}
> *Code:*
> {code}
> PDFMergerUtility pdfMerger = new PDFMergerUtility();
> pdfMerger.addSources(sources);
> pdfMerger.setDestinationStream(mergedPDFOutputStream);
> pdfMerger.mergeDocuments(MemoryUsageSetting.setupTempFileOnly());
> {code}
> both InputStream and OutputStream are ByteArrayInputStream and
> ByteArrayOutputStream. AWS Lambda environment has 512MB space available only
> for /tmp partition. This could be an issue or not I am not sure. And AWS
> lambda do not permit other directory than /tmp partition to create files.
> And while reading into the code I found below piece of code which I think
> always be true. Because if you add some constant amount to an integer that
> will always be constant amount greater than its original value
> in ScratchFile.java => enlarge() method:
> {code}
> if (pageCount + ENLARGE_PAGE_COUNT > pageCount)
> {
> fileLen += ENLARGE_PAGE_COUNT * PAGE_SIZE;
> raf.setLength(fileLen);
> freePages.set(pageCount, pageCount + ENLARGE_PAGE_COUNT);
> }
> {code}
