Mirza Aliev updated IGNITE-20471:
---------------------------------
Description:
*Motivation*
According the logic of invocations of {{TxManagerImpl#finish}}, it is possible
that {{recipientNode}}, which is passed to {{finish}}, could be {{null}}.
Further in the code of {{finish}} method we make
{{replicaService.invoke(recipientNode)}} and this could lead to
{{NullPointerException}}.
UPD1:
It is possible that I was wrong and we even don't reach the code where we call
invoke {{replicaService.invoke(recipientNode)}}, because before we check
{{groups.isEmpty()}} and seems that we go through the other branch.
Need to investigate why I've got {{null}} when run
ItTableRaftSnapshotsTest#entriesKeepAppendedAfterSnapshotInstallation}}
