A CMIS Query with a "null predicate" containing a "multi-valued-column reference" throws an exception. A sample query that demonstrates the problem is listed below as is the exception stack trace. Please confirm this is a bug that I should record in JIRA.
SELECT cmis:objectId FROM cmis:document WHERE dc:subjects IS NOT NULL
