### Search before asking - [x] I had searched in the [issues](https://github.com/apache/fory/issues) and found no similar issues. ### Version OS: `macOS 26.1` Fory: `0.13.1` Java : `java 21.0.3 2024-04-16 LTS` ### Component(s) Java ### Minimal reproduce step ``` import org.apache.fory.Fory; import org.apache.fory.config.Language; import java.util.concurrent.CopyOnWriteArraySet; public class CopyOnWriteArraySetTest { public static void main(String[] args) { Fory fory = Fory.builder() .withLanguage(Language.JAVA) .requireClassRegistration(false) .build(); CopyOnWriteArraySet<String> set = new CopyOnWriteArraySet<>(); set.add("Value1"); set.add("Value2"); byte[] serialized = fory.serialize(set); CopyOnWriteArraySet deserialised = fory.deserialize(serialized, CopyOnWriteArraySet.class); System.out.println("deserialised=" + deserialised); } } ``` ### What did you expect to see? Fory should be able to serialize `java.util.concurrent.CopyOnWriteArraySet` objects. ### What did you see instead? Serialization fails with a `ClassCastException`. <details> <summary>View full stack trace</summary> ``` Exception in thread "main" org.apache.fory.exception.SerializationException: java.lang.ClassCastException: class org.apache.fory.collection.CollectionSnapshot cannot be cast to class java.util.List (org.apache.fory.collection.CollectionSnapshot is in unnamed module of loader 'app'; java.util.List is in module java.base of loader 'bootstrap') at org.apache.fory.Fory.processSerializationError(Fory.java:362) at org.apache.fory.Fory.serialize(Fory.java:331) at org.apache.fory.Fory.serialize(Fory.java:278) at com.fory_tests.CopyOnWriteArraySetTest.main(CopyOnWriteArraySetTest.java:19) Caused by: java.lang.ClassCastException: class org.apache.fory.collection.CollectionSnapshot cannot be cast to class java.util.List (org.apache.fory.collection.CollectionSnapshot is in unnamed module of loader 'app'; java.util.List is in module java.base of loader 'bootstrap') at org.apache.fory.builder.CopyOnWriteArraySetForyCodec_0.writeFields$(CopyOnWriteArraySetForyCodec_0.java:113) at org.apache.fory.builder.CopyOnWriteArraySetForyCodec_0.write(CopyOnWriteArraySetForyCodec_0.java:224) at org.apache.fory.serializer.collection.CollectionSerializers$DefaultJavaCollectionSerializer.write(CollectionSerializers.java:729) at org.apache.fory.Fory.writeData(Fory.java:654) at org.apache.fory.Fory.write(Fory.java:405) at org.apache.fory.Fory.serialize(Fory.java:325) ``` </details> ### Anything Else? _No response_ ### Are you willing to submit a PR? - [ ] I'm willing to submit a PR! -- This is an automated message from the Apache Git Service.
