The isInitialized volatile variable is used to guard state machine initialization, but there's a race condition. Multiple threads could pass the if (!isInitialized) check before any thread sets it to true, leading to multiple initialization attempts. Consider using atomic operations or proper synchronization.

There is a duplicate call to subscriptionStateMachine.completePurchase(purchaseDetail) on consecutive lines. This will cause the state machine to process the same purchase twice, which could lead to unexpected behavior or state inconsistencies.
