The 'package_name' package name defined in the 'property_name' configuration property is not valid.
Explanation
The specified package name cannot be created. Virtual member manager cannot continue because the virtual member manager model schema defined in the package is the core of virtual member manager.
Programmer response
Ensure that the package code is generated correctly. The package code must be generated through Eclipse Modeling Framework (EMF) from XSD files, which include the virtual member manager model schema.
