After merging in my DataValue PR, I noticed some inconsitent results in our 
automated testing.

Prior to merging, all tests passed.

After merging, there was an error in 2 of the configurations:


  *   Java 11, Scala 2.11, Windows-latest 
https://github.com/apache/incubator-daffodil/runs/355023220

  *   Java 11, Scala 2.12, Windows-latest 
https://github.com/apache/incubator-daffodil/runs/355023183


After re-running the checks, the above 2 configurations passed, but there was 
an error on a third configuration:

  *   Java 9, scala 2.11, Ubuntu-latest 
https://github.com/apache/incubator-daffodil/runs/355200232

The 2.11 Windows failure was  a timeout fetching an external resource; which is 
a reasonable cause of a transient failure.

The 2 remaining failures were both a failure to read the 
file:/D:/a/incubator-daffodil/incubator-daffodil/daffodil-test/target/scala-2.11/test-classes/org/apache/daffodil/section06/namespaces/multi_base_09.dfdl.xsd
 file. This file claims to use the UTF-16BE encoding (eyeballing it as a hex 
file; this appears to be accurate. If this were a determinstic failure, I would 
blame encoding issues, but I am not sure what to make about the 
non-deterministic aspect.

Thoughts?
