[jira] [Created] (FLINK-11375) Concurrent modification to slot pool due to SlotSharingManager releaseSlot directly

shuai.xu created FLINK-11375:
--------------------------------

             Summary: Concurrent modification to slot pool due to SlotSharingManager releaseSlot directly 
                 Key: FLINK-11375
                 URL: https://issues.apache.org/jira/browse/FLINK-11375
             Project: Flink
          Issue Type: Bug
          Components: JobManager
    Affects Versions: 1.7.1
            Reporter: shuai.xu


In SlotPool, the AvailableSlots is lock free, so all access to it should in the main thread of SlotPool, and so all the public methods are called throw SlotPoolGateway except the releaseSlot directly called by SlotSharingManager. This may cause a ConcurrentModificationException.
