Resolution:
Modify the code to correct the type and namespace references as required; then recompile.
Example:
The following example shows an internal type, Package 2.B, referenced by a type in a different namespace:
class-id package1.A. method-id main static. invoke type package2.B::Meth1 end method. end class. class-id package2.B internal. method-id Meth1 static. end method. end class.
