We'll get concurrent modification for the list exception in L660 records.size() since there are also other threads updating buffer records. Fixing it by creating a clone of the list, and remove all from the bufferedRecords below. We can optimize it later.

In https://github.com/apache/kafka/pull/13300/files#r1123945673 , we discussed if the null check is necessary, and then decided to drop it. But it turns out it's necessary. Otherwise, NPE will be thrown in some test cases.

With these lines, we got some errors related to "cannot cast the task to StreamTask". Might need to investigate why it will happen. Remove them first to fix the tests.

It failed with "Expected to happen once, However, there were exactly 2 interactions with this mock:". Skip it first.

@lucasbru @guozhangwang @mjsax , I can see there's still a related test failed: But overall, it looks better now. I think we should merge this PR soon, and make further improvement/fix later. WDYT? PS. I'm going to log off now. So I'll leave this PR to you! :) |
|
LGTM, but we will need @mjsax or @guozhangwang to merge this |

I couldn't change this PR, so I added a separate PR for the last failing test: #13519 |

After #13300, there are a bunch of failing tests. Trying to fix them or workaround them to make the CI test healthy.
