In general it is a very bad idea to use the same file name when creating
some update of a document. Thus, you should do something like
PdfCopy copy = new PdfCopy(document1, new
FileOutputStream(getReportLocation() + ".tmp"));
[...]
copy.close();
new File(getReportLocation()).delete();
new File(getReportLocation() + ".tmp").renameTo(new
File(getReportLocation()));
assuming that getReportLocation() returns a String. Otherwise adapt
accordingly.
(Actually you should also add some tests whether delete and rename worked as
desired with some treatment in case of failure.)
If that is absolutely impossible, you might win by moving your new
PdfReader(getReportLocation()) call before the new PdfCopy(document1, new
FileOutputStream(getReportLocation())) line. As the PdfReader constructor
you chose reads all of the PDF into memory, that construction might just
work.
