Can you also add a cpp unit test ?

Sure, I will do it.

Okey!

We are outing for the past few days, and this issue has been delayed. There is indeed a little problem with this PR and I also need to add some c++ unit tests.

Thanks, I added some cpp unit tests, and I think it is ready for review again. :)

The failure of mac-apple-ray-c-plus-plus-and-java is unrelated. BTW, I found that all tests inmac-apple-ray-c-plus-plus-and-java are passed, but the result is still failed. It is very likely that some cases have a segment error when exiting, I will find relevant colleagues to have a look.
