10- * Support re-transform/hot-swap classes with other java agents, and remove the obsolete cache enhanced class feature.
11- * Implement new naming policies for names of auxiliary type, interceptor delegate field, renamed origin method, method
12- access name, method cache value field. All names are under ` sw$ ` name trait. They are predictable and unchanged after
13- re-transform.
14-
15- ```
16- * SWAuxiliaryTypeNamingStrategy
17- Auxiliary type name pattern: <origin_class_name>$<name_trait>$auxiliary$<auxiliary_type_instance_hash>
18-
19- * DelegateNamingResolver
20- Interceptor delegate field name pattern: <name_trait>$delegate$<class_name_hash>$<plugin_define_hash>$<intercept_point_hash>
21-
22- * SWMethodNameTransformer
23- Renamed origin method pattern: <name_trait>$original$<method_name>$<method_description_hash>
24-
25- * SWImplementationContextFactory
26- Method cache value field pattern: cachedValue$<name_trait>$<origin_class_name_hash>$<field_value_hash>
27- Accessor method name pattern: <renamed_origin_method>$accessor$<name_trait>$<origin_class_name_hash>
