Tests failures after adding mockito-inline on Java 21

[MikhailNavitski]

Hi,

It appears that Mockito cannot mock several classes after adding mockito-inline dependency to the project

Mockito cannot mock this class: class org.apache.http.impl.client.CloseableHttpClient.

If you're not sure why you're getting this error, please open an issue on GitHub.

Java : 21 JVM vendor name : Eclipse Adoptium JVM vendor version : 21.0.2+13-LTS JVM name : OpenJDK 64-Bit Server VM JVM version : 21.0.2+13-LTS JVM info : mixed mode, sharing OS name : Windows Server 2022 OS version : 10.0

You are seeing this disclaimer because Mockito is configured to create inlined mocks. You can learn about inline mocks and their limitations under item #39 of the Mockito class javadoc.

The code was successfully run on JDK 11,17

mockito-inline should be updated with a new dependency.

[maryantocinn]

will there be any update for mockito-inline to support JDK 21 in the future?

[viniciusrd10]

I'm also facing this issue. Would be nice to have this update soon.

[RaghavGoyal]

Is there a timeline by which we can expect the update to be released?

[kanikajindal101]

hi Raghav, are u upgrading to java 21? I also need mockito inline

[kanikajindal101]

so mockito inline will not work in java 21...my test cases are failing

[RaghavGoyal]

@kanikajindal101 Yes, I recently upgraded to JDK 21 and that's when this issue is encountered.

For me what worked was to add a byte-butty version that supports Java 21. It is 1.14.17.
