Nicholas Blair commented on PDFBOX-606:
---------------------------------------
The suggestion of the source of the file is really good: the Mac OS X client is
used by a number of our clients to upload content into our repository, so the
possibility exists that we would encounter a malformed "PDF" in this fashion.
I put together a unit test in my environment with the file you uploaded, and I
tried the same test against another file I generated on my own in the same
fashion, but I do not encounter the infinite loop. I do encounter a different
IOException:
java.io.IOException: Error: End-of-File, expected line
at org.apache.pdfbox.pdfparser.BaseParser.readLine(BaseParser.java:1141)
at org.apache.pdfbox.pdfparser.PDFParser.parseHeader(PDFParser.java:294)
at org.apache.pdfbox.pdfparser.PDFParser.parse(PDFParser.java:162)
at org.apache.pdfbox.pdmodel.PDDocument.load(PDDocument.java:847)
at org.apache.pdfbox.pdmodel.PDDocument.load(PDDocument.java:814)
This same Exception and message occurs if I use the original 0.8.0 build I used
when I originally posted the ticket and with the 1.1.0 release available for
download today.
