[jira] [Updated] (PDFBOX-4202) PDDocument is closed before calling
close()
[ https://issues.apache.org/jira/browse/PDFBOX-4202?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Chenyue Gao updated PDFBOX-4202:
--------------------------------
Description:
The following code append PDDocument read from a file to the mainDocument which is passed as parameter. When I save the mainDocument, it throws the exception below.
{code:java}
public static void addPDPage(PDDocument mainDocument, File file, int pagenum) throws IOException {
PDDocument pkDocument = PDDocument.load(file);
PDPageTree pdpageTree = pkDocument.getPages();
pdpageTree.forEach(page -> {
mainDocument.addPage(page);
});
}
{code}
It seems that the pkDocument inside this function automatically closed itself due to Java garbage collection. As a result the mainDocument can't save the page associated with the pkDocument.
A workaround could be to return pkDcoument to the caller and keep the reference at the same level of mainDocument until mainDocument saves
[2018-04-16 11:11:58] COSStream has been closed and cannot be read. Perhaps its enclosing PDDocument has been closed?
