------------------------------------------
Summary: NPE in ItTxDistributedTestThreeNodesThreeReplicas
Key: IGNITE-20251
URL: https://issues.apache.org/jira/browse/IGNITE-20251
Project: Ignite
Issue Type: Bug
Reporter: Vladislav Pyatkov
The exception happens in
{{ItTxDistributedTestThreeNodesThreeReplicas#testSimpleConflict}}, but I'm
sure, it maight occur in any test in this class.
The root cause is using not thread-safe collection for storing cluster services
(HashMap<String, ClusterService>).
