I think this method is not strictly necessary. 

`clb.withInterfaceSymbols(typeNames(interfaces))` can simply be replaced with 


clb.withInterfaceSymbols(interfaces.stream().map(ProxyGenerator::toClassDesc).toList());


`interfaces` should be non-null.  We can add 
`Objects.requireNonNull(interfaces)` in static `generateProxyClass` method.
