w-yfan opened a new issue, #2070: URL: https://github.com/apache/fury/issues/2070
### Search before asking - [x] I had searched in the [issues](https://github.com/apache/fury/issues) and found no similar issues. ### Version fury：0.9.0 jdk: 8 & 11 ### Component(s) Java ### Minimal reproduce step @Data @AllArgsConstructor static class Pojo { private String str; } @Test public void testSerializationUsingJdk11() { // run with jdk11 Fury fury = Fury.builder() .withLanguage(Language.JAVA) .withRefTracking(false) .withCompatibleMode(CompatibleMode.SCHEMA_CONSISTENT) .withAsyncCompilation(true) .build(); fury.register(Pojo.class); byte[] bytes = fury.serialize(new Pojo("test")); writeBytesToFile("example.bytes", bytes); } @SneakyThrows @Test public void testDeserializeUsingJdk8() { // run with jdk8 Fury fury = Fury.builder() .withLanguage(Language.JAVA) .withRefTracking(false) .withCompatibleMode(CompatibleMode.SCHEMA_CONSISTENT) .withAsyncCompilation(true) .build(); fury.register(Pojo.class); byte[] bytes = readBytesFromFile("example.bytes"); System.out.println(fury.deserialize(bytes)); } public static byte[] readBytesFromFile(String filePath) throws IOException { try (FileInputStream fis = new FileInputStream(filePath)) { byte[] data = new byte[fis.available()]; int read = fis.read(data); return data; } catch (IOException e) { throw new IOException("Error reading file: " + e.getMessage()); } } public static void writeBytesToFile(String filePath, byte[] data) { try (FileOutputStream fos = new FileOutputStream(filePath)) { fos.write(data); } catch (IOException e) { System.out.println("Error writing to file: " + e.getMessage()); } } ### What did you expect to see? Complete the deserialization process correctly. ### What did you see instead? The method org.apache.fury.serializer.ObjectSerializer.read() is not used. The stack trace is as follows: java.lang.IndexOutOfBoundsException: readerIndex(8) + length(6) exceeds size(10): org.apache.fury.memory.MemoryBuffer$BoundChecker@12405818 at org.apache.fury.memory.MemoryBuffer$BoundChecker.fillBuffer(MemoryBuffer.java:186) at org.apache.fury.memory.MemoryBuffer.readInt64(MemoryBuffer.java:1431) at org.apache.fury.resolver.MetaStringResolver.readBigMetaStringBytes(MetaStringResolver.java:199) at org.apache.fury.resolver.MetaStringResolver.readMetaStringBytesWithFlag(MetaStringResolver.java:159) at org.apache.fury.resolver.ClassResolver.readClassInfoFromBytes(ClassResolver.java:1732) at org.apache.fury.resolver.ClassResolver.readClassInfo(ClassResolver.java:1666) at org.apache.fury.Fury.readRef(Fury.java:861) at org.apache.fury.serializer.collection.GuavaCollectionSerializers$ImmutableSortedMapSerializer.newMap(GuavaCollectionSerializers.java:377) at org.apache.fury.serializer.collection.MapSerializer.read(MapSerializer.java:67) at org.apache.fury.serializer.collection.MapSerializer.read(MapSerializer.java:27) at org.apache.fury.Fury.readDataInternal(Fury.java:959) at org.apache.fury.Fury.readRef(Fury.java:861) at org.apache.fury.Fury.deserialize(Fury.java:793) at org.apache.fury.Fury.deserialize(Fury.java:714) at com.micar.tsp.realdata.JdkTest.testDeserializeUsingJdk8(JdkTest.java:54) at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method) at sun.reflect.NativeMethodAccessorImpl.invoke(NativeMethodAccessorImpl.java:62) at sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:43) at java.lang.reflect.Method.invoke(Method.java:498) at org.junit.runners.model.FrameworkMethod$1.runReflectiveCall(FrameworkMethod.java:59) at org.junit.internal.runners.model.ReflectiveCallable.run(ReflectiveCallable.java:12) at org.junit.runners.model.FrameworkMethod.invokeExplosively(FrameworkMethod.java:56) at org.junit.internal.runners.statements.InvokeMethod.evaluate(InvokeMethod.java:17) at org.junit.runners.ParentRunner$3.evaluate(ParentRunner.java:306) at org.junit.runners.BlockJUnit4ClassRunner$1.evaluate(BlockJUnit4ClassRunner.java:100) at org.junit.runners.ParentRunner.runLeaf(ParentRunner.java:366) at org.junit.runners.BlockJUnit4ClassRunner.runChild(BlockJUnit4ClassRunner.java:103) at org.junit.runners.BlockJUnit4ClassRunner.runChild(BlockJUnit4ClassRunner.java:63) at org.junit.runners.ParentRunner$4.run(ParentRunner.java:331) at org.junit.runners.ParentRunner$1.schedule(ParentRunner.java:79) at org.junit.runners.ParentRunner.runChildren(ParentRunner.java:329) at org.junit.runners.ParentRunner.access$100(ParentRunner.java:66) at org.junit.runners.ParentRunner$2.evaluate(ParentRunner.java:293) at org.junit.runners.ParentRunner$3.evaluate(ParentRunner.java:306) at org.junit.runners.ParentRunner.run(ParentRunner.java:413) at org.junit.runner.JUnitCore.run(JUnitCore.java:137) at com.intellij.junit4.JUnit4IdeaTestRunner.startRunnerWithArgs(JUnit4IdeaTestRunner.java:69) at com.intellij.rt.junit.IdeaTestRunner$Repeater$1.execute(IdeaTestRunner.java:38) at com.intellij.rt.execution.junit.TestsRepeater.repeat(TestsRepeater.java:11) at com.intellij.rt.junit.IdeaTestRunner$Repeater.startRunnerWithArgs(IdeaTestRunner.java:35) at com.intellij.rt.junit.JUnitStarter.prepareStreamsAndStart(JUnitStarter.java:232) at com.intellij.rt.junit.JUnitStarter.main(JUnitStarter.java:55) ### Anything Else? Both ImmutableCollectionSerializers and SubListSerializers register java.util.ImmutableCollections$SubList, but JDK 8 does not have java.util.ImmutableCollections$SubList, resulting in JDK 8 registering two placeholders. In JDK 11, although java.util.ImmutableCollections$SubList is registered twice, "If a serializer exists before, it will be replaced by the new serializer." This causes the ClassResolver.ExtRegistry#classIdGenerator in JDK 11 to have one less entry compared to JDK 8. The final result: when JDK 8 and JDK 11 are used together, the correct serializers cannot be retrieved through classIdGenerator. ### Are you willing to submit a PR? - [x] I'm willing to submit a PR! -- This is an automated message from the Apache Git Service.
