I tried with this code without trouble:
try
{
PDFMergerUtility pdfMerger = new PDFMergerUtility();
for (int i = 0; i < 30; ++i)
{
String pdfFilename = "test.pdf";
pdfMerger.addSource(pdfFilename);
}
pdfMerger.setDestinationFileName("dest.pdf");
pdfMerger.mergeDocuments();
System.out.println("merged documents");
}
catch (Exception ex)
{
ex.printStackTrace();
}
What JDK are you using? I'm using 1.7.0_71.

New issue with PDFMergerUtility: Take the attached file and make 25
identical copies of it and merge them. Works fine. Add 5 more copies and
you get the following (or something similar):

I tried to pin-point the exact number of files that cause the error but it
sometimes with 26 and failed with 27, but other times 27 worked and 28
failed... Very odd behaivour, but it always happens around the 500MB mark.
