EXCEPTION: javax.xml.transform.TransformerException: Unknown typ e annot

after upgrading to saxonb8, I started getting
                                EXCEPTION:
javax.xml.transform.TransformerException: Unknown type annotation (NULL) in
document instance on my for-each after a sql:query

It fails for all similar for-each's on sql:query's.

Any suggestions, Mike?
