Josh Elser commented on PHOENIX-2930:
-------------------------------------
Thanks for filing, Kevin.
Moved this over to Phoenix. The error is coming directly out of Phoenix, not
Avatica. Not sure if it's a limitation in Phoenix's parser or a bug in the
vendor's version that you're using. That will need to be investigated.
