Mockito-inline has conflict with docker Image

[hudi-bot]

When Mockito-inline is added to hudi-tests-common, this library will be included to tests that run in our docker image in Azure CI, and the underlying library ByteBuddy will have conflicts with the docker image.

 

Currently solution is to avoid adding mockito-inline to hudi-tests-common to avoid the conflicts. But if some tests that run in docker image have to use mockito-inline, we will need to solve the problem.

• Type: Bug
• Fix version(s):
  • 1.1.0

[rangareddy]

This issue was reviewed as part of the JIRA-migrated backlog triage.

Findings: This tracks a build/CI constraint rather than a product defect: adding mockito-inline to hudi-tests-common triggers a ByteBuddy agent self-attachment failure (UnsatisfiedLinkError: [libattach.so](http://libattach.so/) already loaded in another classloader) under the JDK 1.8 Azure CI Docker image. On current master the constraint is still worked around -- hudi-tests-common declares only mockito-core and mockito-junit-jupiter (mockito 5.21.0), not mockito-inline -- so no merged change resolves the underlying conflict. If a test that must run inside the Docker image needs inline mocking, the ByteBuddy/JDK agent-attachment conflict would still have to be solved (or the Docker image's JDK upgraded).

Keeping open as an unresolved build/CI item.
