Description

• 1 Java-only server node
• 2 .NET thick client nodes
• Deploy .NET service: services.DeployNodeSingleton("TestService", TestServiceImpl)
• Cancel .NET service: services.Cancel("TestService")
• Server node crashes with NPE:

java.lang.NullPointerException: Cannot invoke "org.apache.ignite.internal.processors.service.ServiceInfo.name()" because "rmv" is null
        at org.apache.ignite.internal.processors.service.IgniteServiceProcessor.lambda$updateDeployedServices$4(IgniteServiceProcessor.java:1599)
        at java.base/java.util.HashMap.forEach(HashMap.java:1421)
        at java.base/java.util.Collections$UnmodifiableMap.forEach(Collections.java:1553)
        at org.apache.ignite.internal.processors.service.IgniteServiceProcessor.updateDeployedServices(IgniteServiceProcessor.java:1594)

Does not happen if all nodes are .NET nodes, only when the server is Java-only.
