There are some complains from Jenkins, That needs to be checked. Regarding the test for logs. Can use :
GenericTestUtils.LogCapturer.captureLogs(
Can find usage in the code and do similarly.
In general the log change makes sense to me.

Thanks @ayushtkn for your comment, the complains seems not related with the changing code, it seems a little trouble to test this PR, emm , anyway i will try to fix it.

ayushtkn · 2021-12-07T08:53:58Z

hmm, not sure why is it happening, try a rebase on top of present trunk, might help, just a wild guess...
