Unfortunately, this error happens from time to time, and we haven't been able to track it down. Primarily because I don't think anyone has been able to reliably reproduce it. I know I've never actually seen it outside of the CI.
The bug for this is https://issues.apache.org/jira/browse/DAFFODIL-1908 I think the assumption is there is some kindof non-thread-safe code in Xerces (or something that parses the XML) and it hits som race condition that prevents it from detecting that the file is UTF-16, and so can't parse the file correctly. When I see this, I usually just trigger a new build and it goes away so we at least can confirm that the new commit didn't cause any new problems.
