Review Comment:
Yes , I'm sure.
Channel state just allows the data buffer, and doesn't allow the event
buffer. This unit-test checks whether it throw `IllegalArgumentException` when
adding an event buffer.
So I call `processAllRequests` twice, the first one, it's a `start request`
and `add data buffer request`, the second one, it's a `add event buffer
request`.
The first one is normal, and the second one should throw exception. It's
more specific.
