---------------------------------------
Summary: PNG DFDL Schema fails regression testing on 3.3.0-SNAPSHOT
Key: DAFFODIL-2664
URL: https://issues.apache.org/jira/browse/DAFFODIL-2664
Project: Daffodil
Issue Type: Bug
Components: DFDL Schemas, QA
Affects Versions: 3.3.0
Reporter: Mike Beckerle
Just noticed that PNG fails its tests now on 3.3.0-SNAPSHOT as of git hash
62d7bbe69847d85c780f40855c5cfef29a5a7c23
First, it gets a million SDWs, so needs changes to suppress them, or have the
things causing all these warnings fixed.
One example SDW is this, but there are tons of others also:
{code:java}
[error] SchemaDefinitionWarning: Schema Definition Warning: Counterintuitive
placement detected. Wrap the discriminator or assert in an empty sequence to
evaluate before the contents.{code}
The real backtrace is a Runtime SDE at unparse time:
