Nicholas Blair commented on PDFBOX-606:
---------------------------------------
I have a suspicion that the infinite loop may not be a problem for PDFbox to
resolve. Looking closer at the stack trace and the method source, I'm wondering
if the infinite loop was caused by temporary loss of connectivity to the
underlying filesystem while reading the contents of a valid file.
