[jira] [Updated] (IGNITE-15965) Cluster has not been started invariant is broken

["Alexey Scherbakov (Jira)" <ji...@apache.org>]

     [ https://issues.apache.org/jira/browse/IGNITE-15965?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Alexey Scherbakov updated IGNITE-15965:
---------------------------------------
    Description: 
If [1] is called from a message handler just after the cluster start, it will trigger the assertion:
{code:java}
assert localMember != null : "Cluster has not been started";{code}
This is possible because local member is assigned after a {_}cluster.startAwait(){_}, but messages start to process a bit earlier.

Suggested fix - always delegate localMember() call to ClusterImpl.

If [1] is called from a message handler just after the cluster start, it will trigger the assertion:
{code:java}
assert localMember != null : "Cluster has not been started";{code}
This is possible because local member is assigned after a _cluster.startAwait()_, but messages start to process a bit earlier.

Reproducible, for example, by [2]

Suggested fix - always delegate localMember() call to ClusterImpl.
