Michael Stack commented on HBASE-23177:
---------------------------------------
Here is how it looks w/o the patch. Notice how the complaint is about the file
that is referenced when we are opening a Reference:
{code}
java.io.FileNotFoundException:

Here is how it looks like with patch. Note how it says it is opening Reference
-- in particular the bottom half.
