'Make Executable' fails with a Stack Trace
'Make Executable' fails with a Stack Trace indicating 'EpPackager does not understand neverRequired:'.
Resolving the problem
Problem: Attempting to 'Make Executable' from the composition editor gets a Stack Trace with 'EpPackager does not understand neverRequired:'.
Resolution: The neverRequired: method in question should be brought in via the AbtEpPackager class of the AbtRuntimePackaging application. This app is in the "VisualAge for Smalltalk" config map. The neverRequired: method is an accessor method for the neverRequired instance variable of the AbtEpPackager class (which is a subclass of EpPackager). Reloading the config map resolves the problem.
