Maruan Sahyoun commented on PDFBOX-2638:
----------------------------------------
the main issue is that the source documents need to be kept open until the
final document has been stored, which is not the case with your approach. You
might want to review the PDFMerger.java source. Using that your code will become
{code}
PDFMergerUtility merger = new PDFMergerUtility();
for(int i = 0; i < docletNamesAsPdf.length; i++)
{
String sourceFileName = docletNamesAsPdf[i];
merger.addSource(sourceFileName);
}
merger.setDestinationFileName("MergedDoc.pdf");
merger.mergeDocumentsNonSeq(null);
{code}
using it this way PDFMergerUtility, which you are using anyway, will take care
of closing the sources after the job has been done.
Please note that usage questions shall be posted to the users mailing list
[https://pdfbox.apache.org/mailinglists.html].
