Tilman Hausherr commented on PDFBOX-3388:
-----------------------------------------
Just make sure your documents are closed. Most scratchFileBuffer instances are
closed normally, the rest is closed by the gc (and shows the message).
If you really think that some instances are not closed, please create a small
scenario that goes outofmemory just by doing the same thing again and again,
then attach it here, with all that is needed (source code, PDF file(s), java
launch parameters).
> PDFTextStripper - ScratchFileBuffer not closed!

> Key: PDFBOX-3388
> URL: https://issues.apache.org/jira/browse/PDFBOX-3388
> Project: PDFBox
> Issue Type: Bug
> Reporter: Roman Pichlik
> Attachments: CloseablePDFParser.java, PDFStripperTest.java, test.pdf

>
> _PDFTextStripper_ or inherently used classes probably do not close all opened
> streams under all circumstances. You can reproduce that by the following
> snippet of code and the attached PDF file.
> {code}
> try (RandomAccessBuffer rab = new RandomAccessBuffer(is)) {
> PDFParser parser = new PDFParser(rab);
> parser.parse();
> try (COSDocument cosDoc = parser.getDocument();PDDocument pdDoc =
> new PDDocument(cosDoc);){
> PDFTextStripper pdfStripper = new PDFTextStripper();
> pdfStripper.getText(pdDoc);
> }
> } catch (IOException e) {
> throw new RuntimeException(e);
> }
> {code}
