```
    Load the persistent classes named in configuration. This ensures that all subclasses and application identity classes of each type are known in advance, without having to rely on the application loading the classes before performing operations that might involve them.
    
    Parameters:
    
    devpath - if true, search for metadata files in directories in the classpath if the no classes are configured explicitly
    
    envLoader - the class loader to use, or null for default
    
    mustExist - if true then empty list of classes or any unloadable but specified class will raise an exception.
    
    Returns:
    
    the loaded classes, or empty collection if none
