> VM now run in a separate thread, and V_INPUT_DATA_INFORMATION is sent by VM, so it may happen after vertex is initialized. We can't wait for all the V_INPUT_DATA_INFORMATION events available in INITIALIZING state, because it is not know how many V_INPUT_DATA_INFORMATION we may receive, it is determined by VM. So will allow V_INPUT_DATA_INFORMATION happens when vertex is initialized.
