[jira] [Created] (PDFBOX-5111) Premature EOF in RandomAccessReadBuffer using an InputStream

Andreas Lehmkühler created PDFBOX-5111:
------------------------------------------

             Summary: 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
             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.
