OutOfMemoryErrors when trying to convert large PDF to PDF/A

Hi there,

I'm running into OutOfMemoryErrors with a large PDF file (attached). The PDF file is a converted Excel file (converted with Aspose Cells, also attached).

I'm basically just running the PDF -> PDF/A example from your knowledge base (http://www.aspose.com/docs/display/pdfjava/Convert+PDF+to+PDF-A+format):
ByteArrayOutputStream baos = new ByteArrayOutputStream();
ByteArrayOutputStream los = new ByteArrayOutputStream();
Document pdfDocument = new Document(is);
pdfDocument.validate(los, PdfFormat.PDF_A_1B);
pdfDocument.convert(los, PdfFormat.PDF_A_1B, ConvertErrorAction.Delete);
pdfDocument.save(baos);

Exception:
Caused by: java.lang.OutOfMemoryError: GC overhead limit exceeded

OutOfMemoryErrors occured when running with 2, 4, 8 and 16GB of memory for the JVM (Xmx). Tested with Aspose PDF 10.0.1 and 11.4.0.

Kind regards,
Tim
