@Kevin.Herron, any updates on resolution for this bug?
Looks to be an issue others are still bumping into.
Even failing with an informative error in the log would be better than failing silently.
Also, I reported a bug where a commented-out line containing a parameter reference in a named query causes the query execution fail. Perhaps not directly related but similar, maybe due to similar practice/implementation in resolving parameter references without consideration of lines that are commented out.
