             Summary: Big Pdf parsing to text - Out of memory
                 Key: PDFBOX-3284
                 URL: https://issues.apache.org/jira/browse/PDFBOX-3284
             Project: PDFBox
          Issue Type: Bug
          Components: Parsing
    Affects Versions: 2.0.0, 1.8.11, 1.8.10
            Reporter: Nicolas Daniels


I'm trying to parse a quite big PDF (26MB) and transform it to text, however I'm facing a huge memory consumption leading to out of memory error. Running my test with -Xmx768M will always fail. I've to increase to 1500 GB to make it work. 
The resulting text is only 3MB so I don't understand why it is taking so much memory.

The pdf can be found [here|https://www2.swift.com/uhbonline/books/public/en_uk/clr_3_0_stdsmx_msg_def_rpt_sch/sr2015_mx_clearing_3dot0_mdr2_solution.pdf]

My code:

{code:title=Test.java|borderStyle=solid}
@Test
public void testParsePdf_Content_Memory() throws Exception {
{
    InputStream inputStream = getClass().getResourceAsStream("c:/tmp/sr2015_mx_clearing_3dot0_mdr2_solution.pdf");
    try {
			StringWriter writer = new StringWriter();
			FileWriter fileWriter = new FileWriter(new File("c:/tmp/test.txt"));

			PDFTextStripper pdfTextStripper = new PDFTextStripper();
			pdfTextStripper.writeText(PDDocument.load(inputStream), fileWriter);

			fileWriter.close();
		} finally {
			inputStream.close();
		}
}
{code}
