> Fix SSL handshake timeout deadlock in the client connector
> ----------------------------------------------------------
>
> Key: IGNITE-28992
> URL: https://issues.apache.org/jira/browse/IGNITE-28992
> Project: Ignite
> Issue Type: Bug
> Reporter: Nikita Amelchev
> Assignee: Nikita Amelchev
> Priority: Major
> Labels: ise
> Fix For: 2.19
>
> Time Spent: 10m
> Remaining Estimate: 0h
>
> A lock inversion can occur when an SSL client handshake races with its
> timeout. The timeout worker holds the {{CancelableTask}} monitor and waits
> for the SSL lock while closing the session, whereas the NIO worker holds the
> SSL lock and waits for the task monitor in {{{}CancelableTask.close(){}}}.
> This deadlocks both threads and may prevent node shutdown.
