@ZejiaJiang can you please take a look? I think it's one of the tests recently added in #26180

@lmolkova I triggered java-eventhub-ci and java-core-ci of the main branch manually. And java-eventhub-ci of main branch is successful, java-core-ci is failed as well. I need sometime to review your code.

@ZejiaJiang sorry for not being clear - I didn't touch anything related to the test - it's something that reproduces on main - i.e. no need to review my code.

Here's the link to this test stats across branches:

It's pass rate seems to be 75%
