             Summary: Negative TDML Test causes reflective access serialization error using Java 17
                 Key: DAFFODIL-2591
                 URL: https://issues.apache.org/jira/browse/DAFFODIL-2591
             Project: Daffodil
          Issue Type: Bug
          Components: General
    Affects Versions: 3.1.0
            Reporter: Mike Beckerle


I have a reproducible case where I build daffodil from source using Java 17, I publishLocal, then I have a DFDL schema project where one test fails - a TDML-based negative test.

The error has to do with reflective access and object deserialization - there are reflective capabilities that are no longer supported in Java 17; however, the question is why does this one negative TDML test cause this error when many/most other things do not. 

Unfortunately, the DFDL schema for this is non-public. It is called the p8 schema for reference purposes. 

I've listed this as minor priority because using Java 11, or Java 8 for the DFDL schema, this problem does not occur, even if Daffodil itself was built with a Java 17 JVM. 

Note that this test was done AFTER the daffodil git commit bf576e8be961016df11b2b3caf50e0d8f9616867 which adds the "-release 8" to scalac and javac options.

Is it the case that one must use these -release 8 options for a DFDL schema project (which contains scala test driver code) as well in order to avoid this compatibility error?
