Accessing development environment information
Avoid the following methods, as they make references to information that is essentially provided only for the development environment:
•classPool
•instVarNames
•sharedPools
•Library management methods, such as controller, timestamp, and extended
If you attempt to access this information in a packaged image produced by a standard runtime instruction, the attempt will fail because this information is automatically excluded by that instruction.
