             Summary: Invoke statebackend's close() and dispose() in right order
                 Key: FLINK-40921
                 URL: https://issues.apache.org/jira/browse/FLINK-40921
             Project: Flink
          Issue Type: Technical Debt
            Reporter: Zakelly Lan


I found wierd implementation of `StreamOperatorStateHandler::dispose`, which 
register the `close` then `dispose` of each state backend but the actually the 
Guava's closer close things in a reverse order. It seems we should do `close` 
before `dispose`.
