RE: [Non-DoD Source] Re: Update: org.apache.pdfbox.exceptions.WrappedIOException

"That means you bypassed the problem instead of confronting and solving it."
True..

I did as you suggested:
"PDDocument doc = PDDocument.loadNonSeq(new File(...));"

It did not work on the file below.

The pdf I pointed you to yesterday was not a fillable or sign able version that we use here.

Try the one in the link.

Thank you for your help.

Mark....

That means you bypassed the problem instead of confronting and solving it.


Re your code change suggestion - I can't comment it, I suggest you post a diff patch in JIRA. Don't forget to mention what version this is for.
