What steps will reproduce the problem?
1. run "ant browser" on iText 5 branch
2. generate PDF
3. observe NullPointerException in stacktrace
What is the expected output? What do you see instead?
Expected output is a valid PDF file (the file is generated but the PDF is
invalid).
What version of the product are you using? On what operating system?
The iText 5 branch with iText 5.1.3 on Windows 7 64-bit.
Please provide any additional information below.
The problem is caused by an incorrect implementation of
ITextRenderer.provideMetadataToPage. This method sets the byte array "metadata"
even if there is no metadata. In this case a null array is passed to the
pdfWriter who cannot deal with this and crashes. The problem can be easily
fixed by only assigning metadata if there is actually metadata:
private void provideMetadataToPage(PdfWriter writer, PageBox page) throws
IOException {
byte[] metadata = null;
if (page.getMetadata() != null) {
try {
String metadataBody = stringfyMetadata(page.getMetadata());
if (metadataBody != null) {
metadata = createXPacket(stringfyMetadata(page.getMetadata())).getBytes("UTF-8");
}
writer.setPageXmpMetadata(metadata);
} catch (UnsupportedEncodingException e) {
// Can't happen
throw new RuntimeException(e);
}
}
}
