Description

I think we should limit format of resource type name. Otherwise it could be very hard to update in the future after release.

I propose to have format:

[a-zA-Z0-9][a-zA-Z0-9_.-/]*

Adding this check to setResourceInformation might affect performance a lot. Probably we can add to ResourceUtils#initializeResourcesMap when resource types are loaded from config file.
