Description

In all versions of NB > 12.0, I regularly experience problems / exceptions when trying to refactor classes.  In some cases, when moving a class to a new package, NB will scramble the import statements contained in classes that depend on the moved class.  In other cases, when trying to rename a class, NB will rename the file, but fail to rename the class.  And in other cases, when trying to move a class to a new package, NB will generate an exception:
