Description

Currently message groups IDs are simply short values that are manually assigned to every module. This can lead to ID clashes which will lead to message handlers being invoked unexpectedly.

We should find a way to validate group IDs across all modules. One way is to check that message group classes are the same when a handler is registered in the MessagingService.
