Andy Seaborne commented on JENA-1909:
-------------------------------------
It seems that there is a letter {{p}} (which is 112) in the working space files
being read (the file is text lines of hex binary).
That suggests the file has been corrupted in someway.
Could you check the files please? They are {{data-triples.tmp}} and
{{data-quads.tmp}}.
