Description

When checkpoints are aborted due to tasks are finishing when triggering,

1. There is not log in the JM side, which might cause confusion.
2. When the mail is rejected, the exception description for CHECKPOINT_DECLINED_TASK_CLOSING: "Checkpoint was declined (task's operators partially closed)", does not fully match the implementation now.
