PDFBOX-5111: InputStream.available isn't reliable use read() instead to
determine if more data is available
> Premature EOF in RandomAccessReadBuffer using an InputStream
> ------------------------------------------------------------
>
> Key: PDFBOX-5111
> URL: https://issues.apache.org/jira/browse/PDFBOX-5111
> Project: PDFBox
> Issue Type: Bug
> Components: Parsing
> Affects Versions: 3.0.0 PDFBox
> Reporter: Andreas Lehmkühler
> Assignee: Andreas Lehmkühler
> Priority: Major
> Fix For: 3.0.0 PDFBox
>
>
> There are some strange differences in the test results without changing any
> code, e.g. org.apache.pdfbox.pdmodel.font.PDFontTest.testPDFox5048()
> It looks like we can't rely on InputStream.available when reading a pdf from
> a stream (based on an URL) using RandomAccessReadBuffer. According to the
> javadoc ofInputStream.available the behaviour can be different for different
> implementations. In our case it returns 0 and PDFBox doesn't read any more
> data which leads to an incomplete file.
