JCR implementation does not produce events when versioned storage content changes

The org.apache.jackrabbit.test.api.observation.GetUserDataTest.testVersioning() test method (part of the JCR TCK unit test library) attempts to create a new version of a versionable node, and verify that the JCR implementation produces NODE_ADDED events for the changes in content under "/jcr:system/jcr:versionStorage".

At this point, our JCR implementation is not producing events for these versioning operations (and likely not for any changes under the "/jcr:system" area). As such, this test is commented out in our JcrTckTest class.
