------------------------------------------
Summary: Infinite Read Loop
Key: PDFBOX-3605
URL: https://issues.apache.org/jira/browse/PDFBOX-3605
Project: PDFBox
Issue Type: Bug
Components: FontBox
Affects Versions: 2.0.3
Reporter: Cameron Rollheiser
When reading an input file using the BufferedRandomAccesssFile an infinite loop
will occur once the buffer is drained and the value leftover becomes 0, since
the read method will continue to return 0 as the -1 result from fillBuffer() is
never propagated upstream and any code that is executing in a loop using -1 as
an indicator that the file has been fully read will never exit.
An example of where this occurs can be found here:
