cdxf opened a new issue, #1600: URL: https://github.com/apache/incubator-fury/issues/1600
### Search before asking - [X] I had searched in the [issues](https://github.com/apache/incubator-fury/issues) and found no similar issues. ### Version 0.5.0 ### Component(s) Java ### Minimal reproduce step I have the following code: ``` //Fury Configuration public static ThreadSafeFury fury = new ThreadLocalFury(classLoader -> { Fury f = Fury.builder() .requireClassRegistration(false) .withRefTracking(true) .withAsyncCompilation(true) .withCompatibleMode(CompatibleMode.SCHEMA_CONSISTENT) .withJdkClassSerializableCheck(false) .withLanguage(Language.JAVA).withClassLoader(classLoader).build(); f.register(CircularFifoQueue.class); // Function public T get(String key) { try { return (T) fury.deserialize(bytes); } catch (Exception ex) { logger.error("Error deserializing object", ex); return null; } } ... later Queue<Long> result = get(...); ``` ### What did you expect to see? Fury should throw Exception (which is what I am expecting when upgrading to new version and Fury failed to deserialize the byte[] from the old version) instead of silently deserialize the bytes into UnexistedClassSerializers$UnexistedSkipClass ### What did you see instead? It works fine in Fury 0.4.1, but since I upgraded to 0.5.0, my app throws the following errors: > java.lang.ClassCastException: class org.apache.fury.serializer.UnexistedClassSerializers$UnexistedSkipClass cannot be cast to class java.util.Queue (org.apache.fury.serializer.UnexistedClassSerializers$UnexistedSkipClass is in unnamed module of loader org.springframework.boot.loader.launch.LaunchedClassLoader @1d56ce6a; java.util.Queue is in module java.base of loader 'bootstrap') ### Anything Else? If it is expected behavior, where should I look at in the documentation. What should I do instead? Is there any configuration I can change to make it throw Exception instead of returning UnexistedSkipClass ### Are you willing to submit a PR? - [ ] I'm willing to submit a PR! -- This is an automated message from the Apache Git Service.
