I am using Mockito 2.23.4 and byte-buddy 1.9.3 in my project. I wanted to mock final classes and methods, so I used mockito-inline following this post Mockito mock final classes and methods and setting mock-maker-inline inside org.mockito.plugins.MockMaker file in project's src/test/resources/mockito-extensions directory.
I also followed up the post Mockito fails with inlined mocks enabled with Invalid paramter name exception but issue is still there.
But when I run the test I get the below stack trace.
Java HotSpot(TM) 64-Bit Server VM warning: Sharing is only supported for boot loader classes because bootstrap classpath has been appended
Test ignored.
org.mockito.exceptions.base.MockitoException:
Mockito cannot mock this class: class org.elasticsearch.client.RestHighLevelClient.
If you're not sure why you're getting this error, please report to the mailing list.

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.

I tried following dependency settings for byte-buddy as was mentioned in the post mockito fails with inlined mocks :
<dependency>
<groupId>net.bytebuddy</groupId>
<artifactId>byte-buddy</artifactId>
<version>LATEST</version>
</dependency>
But still got no success in resolving the error.My test code and actual method are mentioned in this earlier post of mine: Getting NPE error when trying to mock ElasticClient in Mockito [duplicate]
What can I try next?
