Description

We should print a useful error message if there are multiple message groups in a single compilation unit. This is currently not the case, because we first verify the integrity of network messages, which can fail due to the same reason but with a less helpful message, for example:

apache-ignite-3/modules/network/src/test/java/org/apache/ignite/internal/network/AllTypesMessage.java:[30,8] Conflicting message types in a group, message with type 1 already exists
