Summary: Strange memory behavior on load PDDocument
Key: PDFBOX-3808
URL: https://issues.apache.org/jira/browse/PDFBOX-3808
Project: PDFBox
Issue Type: Bug
Reporter: Sergei Ovchinnikov
Attachments: out2.pdf
It takes ~600mb of memory after loading a single page document (with embeded
fonts). Memory usage grows slightly with the increasing number of pages in the
document. What's wrong with this PDF (I've not noticed strange patterns in PDF
debugger) ?
{code}
public static void main(String[] args) throws Exception {
File in = new File("out2.pdf");
File out = new File("out2_.pdf");
if (!out.exists()) {
out.createNewFile();
}
InputStream inputStream = null;
OutputStream outputStream = null;
System.out.println("start pdf 2 pdf");
PDDocument doc = null;
try {
final long startTime = System.currentTimeMillis();
inputStream = new BufferedInputStream(new FileInputStream(in));
outputStream = new BufferedOutputStream(new FileOutputStream(out));
System.out.println(MessageFormat.format("before loading
totalMemory: {0}, free: {1}, max: {2}",
Runtime.getRuntime().totalMemory(),
Runtime.getRuntime().freeMemory(),
Runtime.getRuntime().maxMemory()));
doc = PDDocument.load(inputStream,
MemoryUsageSetting.setupTempFileOnly());
System.out.println(MessageFormat.format("after loading totalMemory:
{0}, free: {1}, max: {2}",
Runtime.getRuntime().totalMemory(),
Runtime.getRuntime().freeMemory(),
Runtime.getRuntime().maxMemory()));
System.out.println("save");
doc.save(outputStream);
final long endTime = System.currentTimeMillis();
System.out.println(MessageFormat.format("it takes {0,number,#.###}
s to handle pdf 2 pdf ",
(endTime - startTime) / 1000.));
} finally {
try {
if (doc != null) {
doc.close();
}
} finally {
IOUtils.closeQuietly(inputStream);
IOUtils.closeQuietly(outputStream);
}
}
System.out.println("ok");
}
{code}
