Can you try a higher -Xmx value?

Hi,
I was running some unit tests to see if the fix for the following bug https://issues.apache.org/jira/browse/PDFBOX-1426 was working for our project.
I wanted to test as well that I was not introducing some problems through using an unreleased version. 

The following error occurred while converting PDF to TIF

Caused by: java.lang.OutOfMemoryError: Java heap space

My method for conversion:

            PDDocument pdfDoc = *null*;

*try*{

/LOG/.debug("convertPDFtoTIFF input size: "+ fis.available());

IIORegistry registry = IIORegistry./getDefaultInstance/();

registry.registerServiceProvider(*new*TIFFImageWriterSpi());

registry.registerServiceProvider(*new*TIFFImageReaderSpi());

TIFFImageWriterSpi tiffspi = *new*TIFFImageWriterSpi();

ImageWriter writer = tiffspi.createWriterInstance();

ImageWriteParam param = writer.getDefaultWriteParam();

param.setCompressionMode(ImageWriteParam./MODE_EXPLICIT/);

param.setCompressionType("LZW");

param.setCompressionQuality(0.3f);

                  ios = ImageIO./createImageOutputStream/(fos);

writer.setOutput(ios);

writer.prepareWriteSequence(*null*);

PDFParser parser = *new*PDFParser(fis);

parser.parse();

                  pdfDoc = parser.getPDDocument();

*int*pageNum = pdfDoc.getNumberOfPages();

                  }

                  Date t2 = *new*Date();

*long*diff = Math./abs/(t1.getTime() - t2.getTime());

/LOG/.debug("Total Pages: "+ pageNum);

            }*catch*(Throwable t){

/LOG/.error("PDF Splitter Service failed to transform PDF to tiff");
*throw**new*IllegalArgumentException("PDF Splitter threw an exception while processing the PDF ",t); 

            } *finally*{

*if*(pdfDoc != *null*) {

pdfDoc.close();

                  }

*if*(ios != *null*) {

ios.flush();

ios.close();

                  }

*if*(fos != *null*) {

fos.flush();

                  }

            }

      }
I cannot attach the PDF as it contains customer data but I am trying to recreate this error with a different PDF. 

I hope you can help me on this matter. This would be really great.

Thank you and kind regards,

Francesca
