Merging PDF using PDFBOX give scratch file size of 65536 error on AWS lambda only

We are using PDFBOX to merge two PDFs

  1. File 1 : 35 KB
  2. File 2 : 32 KB

While merging, I am getting the error Expected scratch file size of 65536 but found 61440

I am using MemoryUsuageSetting using tempfile for the merge, as in

pdfMerger.mergeDocuments(MemoryUsageSetting.setupTempFileOnly());

Below is the code in my merge routine 

List<InputStream> sources (inputsteam of my files to merge)
mergedPDFOutputStream = new ByteArrayOutputStream();
cosStream = new COSStream();
PDFMergerUtility pdfMerger = new PDFMergerUtility();
pdfMerger.addSources(sources);
pdfMerger.setDestinationStream(mergedPDFOutputStream);
pdfMerger.mergeDocuments(MemoryUsageSetting.setupTempFileOnly());

While calling the above merge routine in AWS lambda, we are getting the same error (Expected scratch file size of 65536 but found 61440)

However, if I call our PDF merge routine in a Java main program in my local machine, the files are generated successfully.

Below is the stack trace of the error

We are using PDFBox version 2.0.12

Can someone please guide on resolving this issue?

Thanks, Anjana

I had the same issue in AWS, just changed the memory usage for the merge from 

pdfMerger.mergeDocuments(MemoryUsageSetting.setupMixed(MEMORY_USE));

to

pdfMerger.mergeDocuments(MemoryUsageSetting.setupMainMemoryOnly());

And it worked for AWS Lambda,

Hope this helps someone else.

Regards
