Description

I get this with the attached file:

Exception in thread "main" java.util.NoSuchElementException

While the 1.8 version recovers, the 2.0 version doesn't. My fix prevents the exception and puts out a warning. Adobe Reader can render the file, although there is a weird glyph between "program" and "administration", and between "claimants" and "eligibility".
