    Description

      Some commands throws NullPointerException when CLI is disconnected from controller and user tries to use tab completion (so far I found these: ls, read-attribute, read-operation).

      No exception is thrown with 6.4.0.GA

          Bug - A problem that impairs or prevents the functions of the product. JBEAP-232 Some commands throws NPE on tab completion once disconnected

          • Major - To be worked after higher priority work items are addressed. When the severity is high and the effort to change it is low to moderate, this term is chosen. Issues in this category likely have an existing workaround but implementation or execution may be non-trivial.
