---------------------------------------
Summary: NITF cyclic deadlock regression
Key: DAFFODIL-2666
URL: https://issues.apache.org/jira/browse/DAFFODIL-2666
Project: Daffodil
Issue Type: Bug
Components: DFDL Schemas
Affects Versions: 3.3.0
Reporter: Mike Beckerle
The public NITF schema fails.
It gets a bunch of warnings that need to be suppressed via a config file, but
it also gets this deadlock:
