MySQL useCursorFetch property and Grails 2.2.4

Just hit a problem with using the useCursorFetch property in Grails 2.2.4. It may be present in earlier versions of Grails 2, but this was working up through Grails 1.3.9. I'm upgrading a Grails 1.3.9 application to Grails 2.2.4 and hit the following runtime exception when the JDBC URL has the useCursorFetch property set to true.

Removing the property from the JDBC URL resolves the issue. Need to do more research into why this is happening.
