>          Components: Parsing
>    Affects Versions: 0.8.0-incubator
>            Reporter: Mel Martinez
>             Fix For: 1.0.0

> The class:     org.apache.pdfbox.pdfparser.PDFXrefStreamParser
> uses an unbounded iterator in it's parser method.
> Specifically, line 100 should be changed from:
>             while(pdfSource.available() > 0)
> To
>             while(pdfSource.available() > 0 && objIter.hasNext())
> Not having this check causes line 115 to blow up with a NoSuchElementException.
> I will attach a test file that triggers the problem (during Text extraction) and also a patched version of PDFXrefStreamParser.java.
