Subject Re: build failure in master
Date Fri, 20 Sep 2019 12:43:00 GMT
PDFBox Colleagues,
  Do you know of any diffs between Java 8 and 11 that would affect the
extraction of images from PDFs?  Dan is getting a build failure
because of a hash mismatch.
  Thank you.

           Best,

                   Tim
