[jira] [Comment Edited] (IGNITE-7972) NPE in TTL manager.

["Andrew Mashenkov (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/IGNITE-7972?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16435676#comment-16435676 ]

GridCacheUtils.unwindEvicts() takes cache contexts from SharedContext and tries to evict entries from known caches.

Possible issue here is that cache context was published to SharedContext before it's managers (incl. TtlManager) has been started.
 There is a guarantee that if cache context.started()==true then all it's managers is started as well.

Seems, GridCacheUtils.unwindEvicts() should just check if cache context is started.
