Hi,

Hi @kressi ,

I tested your sample project using the following plugin and it seems to work with jdk17 (see #33 for more information).

            <plugin>
                <groupId>org.apache.maven.plugins</groupId>
                <artifactId>maven-surefire-plugin</artifactId>
                <version>2.22.2</version>
                <configuration>
                    <argLine>-XX:+AllowRedefinitionToAddDeleteMethods</argLine>
                </configuration>
            </plugin>

Please confirm that it also works for you ?
thanks.

@kressi ,

so, I'm closing this issue. For the reference, here is the modified pom.xml which I think solves the problem
The documentation has been updated with a special note about using JDK13+ versions in #312.
(reopen this issue if needed, thanks).
