Since "subpackages" don't have access to package-private parent classes (as the tableproviderwrapper and the IO stub are within different packages), going package-private with the tableproviderwrapper doesn't seem to give access to the IO table provider stubs. ---------------------------------------------------------------- This is an automated message from the Apache Git Service.
