[OlgaMaciaszek]

@SivaTharun , thanks for reaching out. @maniotie is already working on this issue for now. If not all modules are converted, I will get back to you here.

[OlgaMaciaszek]

@maniotie is now working on reducing method and class visibility after the conversion to JUnitJupiter.

Is anybody working on this?

[OlgaMaciaszek]

I don't think anybody is at the moment. They are only a few test left, but possibly the ones that were proving tricky during the previous work done by contributors. Would you like to work on it @ThomasTopuz ?

The remaining tests use the deprecated ModifiedClassPathRunner class. It would be possible to replace it with ModifiedClassPathExtension, but this class has a package-access level. How could we solve this? Should I create an issue and patch in the spring-cloud-commons project?

[OlgaMaciaszek]

Right, @deii. Have created: spring-cloud/spring-cloud-commons#1358.

[OlgaMaciaszek]

It's merged now. @deii @ThomasTopuz Let me know if any of you would like to work on this.
