      Description

      In the latest regression run with PDFBox's 2.x branch, we're now getting very slow processing on a truncated PDF with PDFBox app's ExtractText:

      http://162.242.228.174/docs/truncated_pdfs/commoncrawl2_likely_broken/7K/7KK53NK5PVKOUGDSQ4FK6542BNPC4SWB

      Turns out this is not an infinite loop. After 4.5 minutes, ExtractText eventually ended with:

      Exception in thread "main" java.io.IOException: Missing root object specification in trailer.
