Hi All I am migrating all my code to JDK 21. I have just run the tests and I have found this issue with Byte Buddy. Looks like as this version doesn't support JDK 21.
I am using Mockito-inline 5.2.0, Do you know if exist any mockito version that support JDK 21? or if there is any workaround?
Best Regards
This problem should never occur for javac-compiled classes. This problem has been observed for classes that are:
- Compiled by older versions of scalac
- Classes that are part of the Android distribution

Mockito depends on the latest version of ByteBuddy which supports JDK 21. Make sure that in your dependency resolution, the version of ByteBuddy transitively resolves to the correct version. Most likely a different dependency pulls in an old version.

this is the dependencies of mockito-core 5.2.0, as you can see the version of bytebuddy is hardcoded to 1.14.1

We stopped publishing mockito-inline as a separate artifact as the inline mockmaker is the default since Mockito 5. You can now use mockito-core with its latest version. For more info see https://javadoc.io/doc/org.mockito/mockito-core/latest/org/mockito/Mockito.html#0.2

Hi Pablo,
I have the same issue as you when starting to use jdk21 for my bazel repo. Wonder how did you end up resolving the error?

Also, changing byte-buddy-agent and byte-buddy to 1.41.3 doesn't help https://team-review.git.corp.google.com/c/adm-cloud-git-owners/scp/+/2466209/4/licenses/licenses.xml.
