currently we allow an arbitrary module alias to be defined with a deployment/subdeployment in jboss-deployment-structure.xml. The ServiceModuleLoader will however only accept module identifiers that have the 'deployment.' prefix.
I believe the 'deployment.' prefix is an unnecessary constraint for deployed module aliases. Deployments should be able to define any alias. This would allow for a deployment to get 'promoted' to a system module without breaking clients. A module alias should be unique, if a deployment defines an alias of an already existing module it should fail. System modules cannot have dependencies on deployment modules.
This
change, provides a fallback in the ServiceModuleLoader that allows deployment modules to be loaded by their alias even if they don't have the 'deployment.' prefix. Unless I'm mistaken it only applies to inter deployment dependencies.
