[Question] How to force codegen serializer for custom JDK serialization?

### Question

Hi,

Fury shows the following (correct) warning for one of my classes:

> class xy.SimplePrincipalCollection customized jdk serialization, which is inefficient. Please replace it with a org.apache.fury.serializer.Serializer or implements java.io.Externalizable.

I have no control over this class and cannot write an efficient custom serializer because internals cannot be accessed without reflection. How can I force Fury to use the default JIT/Codegen serializer for this class?

Start by tracing Fury's warning for customized JDK serialization and the serializer-selection path for the affected Java class. The issue names no source files or tests, so first identify the configuration or entry point that controls JIT/Codegen selection; done would require a documented or implemented way to force that serializer without access to the class internals.
