Life cycle state change behavior
Hi Reka, Isuru,
Below is the stack trace I got when I undeployed an application. Please
note that status change from Terminating to Terminating. Application does
not reached Terminated event thereafter. Is this a normal state change?

Its the same explanation. This is because the operation is carried out by
multiple threads. And, you can't see the Terminated update since the member
is removed from the Topology.

Hi Isuru,
What I pointed out is not multiple logs. Status is changing to Terminating
to Terminating which is transition on same state. Other thing is state did
not become Terminated ever.
Touched, not typed. Erroneous words are a feature, not a typo.

Hi Udara,
AFAIU, this is normal.
In the single JVM setup, there are multiple message processors for one type
running, but they are updating a single Topology model. Therefore, the
first one updates it, and the subsequent ones see that it has been updated
already. That is why you are seeing multiple transitions to the same state.
