> 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 1500M to make it work. 
> The resulting text is only 3MB so I don't understand why it is taking so much memory.
> I've tested this code over 1.8.10, 1.8.11 & 2.0.0 with same result.
> 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 = new FileInputStream("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}
