Description

Able to repeat with command line.  Unfortunately, the only files that repeat this are from a customer, and contain sensitive information.  The file opens without error in Acrobat Reader and Mac Preview.  The desired result is that any corrupt portions of the PDF are skipped, so that we can use what text is extractable.

Unfortunately, I still get an error when using the -force option.

We get the following stack trace:
