Major Description
CoreAdminHandler.handleMergeAction is generating NullPointerException
If directoryFactory.get(...) in handleMergeAction throws an exception the original error is lost as the finally clause will attempt to clean up and generate an NPE. (notice that "dirsToBeReleased" is pre-allocated with nulls that are not filled in)
