[GitHub] [flink] zhijiangW opened a new pull request #10840: [FLINK-15444][runtime] Make the component AbstractInvokable in CheckpointBarrierHandler NonNull

zhijiangW opened a new pull request #10840: [FLINK-15444][runtime] Make the component AbstractInvokable in CheckpointBarrierHandler NonNull
URL: https://github.com/apache/flink/pull/10840
 
 
   ## What is the purpose of the change
   
   *The current component `AbstractInvokable` in `CheckpointBarrierHandler` is annotated as `@Nullable`. Actually in real code path it is passed via the constructor and never be null. The nullable annotation is only used for unit test purpose. But this way would mislead the real usage in practice and bring extra troubles, because you have to alway check whether it is null before usage in related processes.*
   
   *We can refactor the related unit tests to implement a dummy `AbstractInvokable` for tests and remove the @Nullable annotation from the related class constructors.*
   
   
   ## Brief change log
   
     - *Remove `Nullable` annotation from `CheckpointedInputGate`*
     - *Remove `Nullable` annotation from `CheckpointBarrierHandler`*
     - *Introduce `DummyCheckpointInvokable` for tests*
   
   ## Verifying this change
   
   This change is a trivial rework / code cleanup without any test coverage.
