We recently upgraded springBoot version to 3.2, and Java 21 64 bit.
We observed the LifecycleObjectSupport object log was output every time an Event was notified in Spring StateMachine.
2023/12/20,13:48:06.600 INFO [DeviceBroker ] [nio-8080-exec-7] mework.statemachine.support.LifecycleObjectSupport : stopped org.springframework.statemachine.support.DefaultStateMachineExecutor@7efa3f63 2023/12/20,13:48:06.600 INFO [DeviceBroker ] [nio-8080-exec-7] mework.statemachine.support.LifecycleObjectSupport : stopped ATTACHED / / uuid=da1c1d7d-7d54-4484-bf49-d224f7324a3e / id=null

Currently it says eventNotAccepted in BaseStateMachine.
WARN [DeviceBroker ] [nio-8080-exec-7] .device.base.statemachine.BaseStateMachineListener : [eventNotAccepted] Device- Cat event not accepted: GenericMessage [payload=CONNECT, headers={id=351edf7d-8504-39dc-29cd-973600fdba5a, timestamp=1708581146172}]

This is warning message in the log also LifecycleObjectSupport object is not there now. We want to know the why and its impact . is it expected in current version ?

I don't think this has anything to do with Spring Boot. Please open an issue on the statemachine tracker.
