Extracting from [FLINK-25185 discussion|https://issues.apache.org/jira/browse/FLINK-25185?focusedCommentId=17462639&page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel#comment-17462639]

On checkpoint abortion or any failure in AsyncCheckpointRunnable,
it discards the state, in particular shared (incremental) state.

Since FLINK-24611, this creates a problem because shared state can be re-used for future checkpoints. 

Needs confirmation.
