List of classes that must implement Serializable because they are marshalled 
using JdkMarshaller:
- org.apache.ignite.internal.processors.service.ServiceDeploymentProcessId (see 
KillCommandDdlIntegrationTest)
- 
org.apache.ignite.internal.processors.service.ServiceSingleNodeDeploymentResult 
(see KillCommandDdlIntegrationTest)
- 
org.apache.ignite.internal.processors.query.stat.messages.StatisticsObjectData 
(see StatisticsCommandDdlIntegrationTest)
- 
org.apache.ignite.internal.processors.query.stat.messages.StatisticsColumnData 
(see StatisticsCommandDdlIntegrationTest)
- 
org.apache.ignite.internal.processors.query.stat.messages.StatisticsDecimalMessage
 (see StatisticsCommandDdlIntegrationTest)
- 
org.apache.ignite.internal.processors.query.stat.messages.StatisticsKeyMessage 
(see StatisticsCommandDdlIntegrationTest)

> Currently Message interface extends Serializable. But Ignite use our custom 
> logic for message serialization (MessageSerializer of Message#writeTo, 
> Message#readFrom). Then usage of Serializable is useless, but misleading. 
> What should be done:
>  # Remove Serializable interface from 
> org.apache.ignite.plugin.extensions.communication.Message class.
>  # Remove serialVersionUID from all classes implements the interface. 
>  # If some classes requires java serialization (overrides 
> writeObject/writeReplace/writeExternal methods) - let's investigate this 
> cases.
