BF12 commented on PDFBOX-3377:
------------------------------
I actually provided the file command output so you have a better view of all
the files that are in the font directory on an AIX box.
That being said, I checked for .ttf, .otf, .pfb and .ttc files, and I confirm
that the only ones that are ascii text are the 3 I provided earlier.
Not sure why in your case you get a stack trace while it goes in an infinite
loop on my system. We are running on WebSphere Application Server, on an IBM
JVM, so that might be why.
Thanks for the updated code, we will test it ASAP and report back. Probably
tomorrow.
