------------------------------------
Priority: Major (was: Minor)
> [Thin client] NullPointerException while executing
> putAllConflict/removeAllConflict requests

> Key: IGNITE-28348
> URL: https://issues.apache.org/jira/browse/IGNITE-28348
> Project: Ignite
> Issue Type: Bug
> Reporter: Mikhail Petrov
> Assignee: Mikhail Petrov
> Priority: Major
> Labels: ise
> Fix For: 2.19

> We need to fix flaky DataReplicationOperationsTest. See
> https://ci2.ignite.apache.org/project.html?projectId=IgniteTests24Java8&testNameId=-2244900484209781876&tab=testDetails
> for more details.
> The cause of test failure is the ClientCacheRequest#cachex method which
> searches for the requested cache descriptor and, if present, unconditionally
> obtains corresponding cache proxy.
> The cache proxy may not be initialized even if the cache descriptor is
> present (PME caused by cache start is still in progress). In this case
> IgniteEx#cachex returns null causing a NullPointerExeption.
> The test also facing the problem when node0 starts the cache method.
> createCache method returns but PME callbacks have not finished on the node1.
> The thin client sends cache request to node1 and got NPE - it is possible
> because of partitionAwareness/clusterDiscovery features.
> We can consider the following ways to fix this issue:
> - simply double check the cache existence after both calling
> ClientCacheRequest#cacheDescriptor and IgniteEx#cachex.
> - try using the cache proxy initialization wait mechanism - see
> GridCacheProcessor#awaitInitializeProxy
