Describe the bug
After bumping up the version to 2.17.1 I'm not longer able to deserialize values serialized with the version 2.15.4.
Moreover, values serialized with the new version (2.17.1) give error when deserializing.
Version Information
2.17.1
Reproduction
package com.kze.test;
import com.fasterxml.jackson.annotation.JsonTypeInfo;
import com.fasterxml.jackson.core.JsonParser;
import com.fasterxml.jackson.databind.JavaType;
import com.fasterxml.jackson.databind.ObjectMapper;
import com.fasterxml.jackson.databind.jsontype.BasicPolymorphicTypeValidator;
import com.fasterxml.jackson.databind.jsontype.PolymorphicTypeValidator;
import com.fasterxml.jackson.databind.jsontype.impl.StdTypeResolverBuilder;
import java.io.IOException;
import java.util.EnumSet;
import static com.fasterxml.jackson.annotation.JsonTypeInfo.As.PROPERTY;
import static com.fasterxml.jackson.databind.ObjectMapper.DefaultTyping.NON_FINAL;
import static com.kze.test.TestClazz.TestEnum.TEST_ENUM_VALUE;
public class TestClazz {
public enum TestEnum {
TEST_ENUM_VALUE
}
public static void main(String[] args) throws IOException {
ObjectMapper mapper = new ObjectMapper();
final PolymorphicTypeValidator validator = BasicPolymorphicTypeValidator.builder()
.allowIfSubType("com.kze.test")
.allowIfSubType("java")
.build();
ObjectMapper.DefaultTypeResolverBuilder resolverBuilder
= new ObjectMapper.DefaultTypeResolverBuilder(NON_FINAL, validator) {
@Override
public boolean useForType(JavaType t) {
return true;
}
};
StdTypeResolverBuilder stdTypeResolverBuilder = resolverBuilder
.init(JsonTypeInfo.Id.CLASS, null)
.inclusion(PROPERTY);
mapper.setDefaultTyping(stdTypeResolverBuilder);
mapper.configure(JsonParser.Feature.INCLUDE_SOURCE_IN_LOCATION, true);
EnumSet<TestEnum> input = EnumSet.of(TEST_ENUM_VALUE);
String inputJson = mapper.writeValueAsString(input);
System.out.println(inputJson);
Object inputDeserialized = mapper.readValue(inputJson, Object.class);
System.out.println(inputDeserialized);
}
}Version 2.15.4 output
["java.util.EnumSet<com.kze.test.TestClazz$TestEnum>",["TEST_ENUM_VALUE"]]
[TEST_ENUM_VALUE]
Version 2.17.1 error:
