    KAFKA-6148; ClassCastException in connectors that include kafka-clients 
packages (#4457)
    
    Exclusion for packages that need not be loaded in isolation needs to be 
extended to all the `org.apache.kafka` packages (that do not belong to 
transforms and the other whitelisted packages). Most notably, this refers to 
any classes in `kafka-clients` package.
