Close a PDF file when read it from java

I am reading some text from a pdf file 

try { 
    File pdfFile = new File("ffile.pdf");
    PDFParser parser = new PDFParser(new FileInputStream(pdfFile));     
    parser.parse();
    COSDocument cosDoc = parser.getDocument();
    PDFTextStripper pdfStripper = new PDFTextStripper();
    PDDocument pdDoc = new PDDocument(cosDoc);
    //do sth

} catch (Exception e) {
    System.err.println("An exception occured in parsing the PDF Document."
                    + e.getMessage());
}

and some times I get this error: 

WARNING [Finalizer] org.apache.pdfbox.cos.COSDocument.finalize Warning: You did not close a PDF Document

I read a similar qustion here where it says I have to close the opened file. So, I added 

finally{
    pdfFile.close();  //<-
}

but Netbeans mark it with error the close() saying that can't find symbol. So what I have to close? I tried also parser.close() but this line is also marked with error from Netbeans.

You are using an outdated way to open files. This is the correct way to do it (exception handling omitted):

File pdfFile = new File("ffile.pdf");
PDDocument pdDoc = PDDocument.load(pdfFile);
PDFTextStripper pdfStripper = new PDFTextStripper();
//....
pdDoc.close();

Use the close() method of the PDDocument or the COSDocument instance (in both cases the close method of the COSDocument object is called)
