[jira] [Commented] (OAK-1304) createQuery(query,Query.JCR_JQOM) is returning QueryImpl instead of QueryObjectModel

Thomas Mueller commented on OAK-1304:
-------------------------------------

You are right, the spec requires this. I wasn't actually aware about that. I think there are no tests in Jackrabbit 2.x about it.

If we want to support it in Oak: Implementing it would require a SQL-2 parser in oak-jcr, so there would be some code duplication, as there is already a SQL-2 parser, in oak-core. The parser in oak-core can't be used because it doesn't return in a QOM tree but an AST. Also, the parser in oak-core is more powerful (it supports features that can't be mapped to a QOM tree). In this case, I think it would be better to duplicate the code.

> According to the spec queryManager implementation will return an instance of QueryObjectModel when passing Query.JCR_JQOM as the language.
