Fixes #13849 Fixes #14848 ### Motivation #11570 adds a `testSendAsyncCloseAsyncConcurrentlyWithLazyProducers` for the case that some `sendAsync` calls that are invoked after `closeAsync` is called in another thread must complete with `ResultAlreadyClosed`. It's flaky because the synchronization between two threads is not strict. This test uses `sendStartLatch` for the order of `sendAsync` and `closeAsync`: ``` sendAsync 0,1,...,9 -> sendStartLatch is done -> closeAsync ``` However, it cannot guarantee the rest `sendAsync` calls happen after `closeAsync` is called. If so, all `sendAsync` calls will complete with `ResultOk`. On the other hand, this test is meaningless because it requires strict synchronization between two threads so there is no need to run `sendAsync` and `closeAsync` in two threads. The verification of this test is also wrong, see https://github.com/apache/pulsar/issues/13849#issuecomment-1079098248. When `closeAsync` is called, the previous `sendAsync` calls might not complete, so all `sendAsync` will complete with `ResultAlreadyClosed`, not only those called after `closeAsync`. In addition, this PR also tries to fix the flaky `testReferenceCount`, which assumes too strictly. ### Modifications - Remove `testSendAsyncCloseAsyncConcurrentlyWithLazyProducers` - Only check the reference count is greater than 0 instead of equal to 1 ### Documentation Check the box below or label this PR directly.
