Since this is the stable release, what I am doing wrong in the initial build?

commented

The Failed to resolve 'FakeType' into class is not a test failure/error but an error log during test (updated to warn in #4596).

We can not reproduce your failed test testBooleanAdditionalPropertiesSerialization, can you detail which command, java and maven version you are using when building, along with any significant details?

building with java 11+ with command ./mvnw clean install works fine

commented

The command was ./mvnw clean install and these versions:
java -version
java version "21.0.1" 2023-10-17 LTS
mvn -v
Apache Maven 3.8.4 (9b656c72d54e5bacbed989b64718c159fe39b537) Maven home: C:\apache-maven-3.8.4 Java version: 18, vendor: Oracle Corporation, runtime: C:\Program Files\Java\jdk-18 Default locale: en_US, platform encoding: UTF-8 OS name: "windows 10", version: "10.0", arch: "amd64", family: "windows"
When I reverted to Java version 11 the above error no longer appeared.

Thanks for details, reopening as issue is reproducible when building/testing with Java 21+. Issue is related to not ignored List newly introduces properties first and last in one test.
