[jira] [Created] (DAFFODIL-2576) improve "no forward progress" diagnostic message

Mike Beckerle created DAFFODIL-2576:
---------------------------------------

             Summary: improve "no forward progress" diagnostic message
                 Key: DAFFODIL-2576
                 URL: https://issues.apache.org/jira/browse/DAFFODIL-2576
             Project: Daffodil
          Issue Type: Improvement
          Components: Diagnostics
    Affects Versions: 3.1.0, 3.2.0
            Reporter: Mike Beckerle


Due to a user complaint that it wasn't understandable, I think we need to fix the daffodil error message about no forward progress be sure to say: 

1) the error is about the array element
2) the array element that parsed successfully consumed zero data
3) since the array is unbounded maxOccurs, you are in an infinite loop, as any further attempt to parse will make no forward progress through the data.
