Henri Biestro resolved JEXL-162.
--------------------------------
       Resolution: Fixed
         Assignee: Henri Biestro
    Fix Version/s: 3.0

Point taken; the empty/size operators are back to being lenient.
Overloads may throw exceptions that will be handled specifically. 

Added specific exception/method for operator error handling, updated behavior to be as lenient as 2.x, added test, clarified doc and updated changes.
